Submission guidelines

Instructions to Authors

Aims and Scope

The Journal of Gastroenterology, which is the official publication of the Japanese Society of Gastroenterology, publishes Original Articles (Alimentary Tract/Liver, Pancreas, and Biliary Tract), Review Articles, Letters to the Editors and other articles on all aspects of the field of gastroenterology. Significant contributions relating to basic research, theory, and practice are welcomed. These publications are designed to disseminate knowledge in this field to a worldwide audience, and accordingly, its editorial board has an international membership.

Prerequisites for Publication

The editors of the Journal of Gastroenterology abide by the recommendations formulated by the International Committee of Medical Journal Editors (http://www.icmje.org/). A Certificate of Exclusive Submission and Disclosure of Conflict of Interest, available on-line (http://www.springer.com/535), must be submitted to the journal's editorial office by uploading it as a PDF via Editorial Manager.

IMPORTANT: Upon receipt of a Certificate of Exclusive Submission and Disclosure of Conflict of Interest, manuscripts are officially recognized as submissions.

Ethical Standards

Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments.

It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or failure to fulfill the above-mentioned requirements. Authors should also follow the guidelines for the care and use of laboratory animals of their institution or national animal welfare committee.

Ethical Responsibilities of Authors

This journal is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct.

Authors should refrain from misrepresenting research results which could damage the trust in the journal, the professionalism of scientific authorship, and ultimately the entire scientific endeavour. Maintaining integrity of the research and its presentation is helped by following the rules of good scientific practice, which include*:

  • The manuscript should not be submitted to more than one journal for simultaneous consideration.
  • The submitted work should be original and should not have been published elsewhere in any form or language (partially or in full), unless the new work concerns an expansion of previous work. (Please provide transparency on the re-use of material to avoid the concerns about text-recycling (‘self-plagiarism’).
  • A single study should not be split up into several parts to increase the quantity of submissions and submitted to various journals or to one journal over time (i.e. ‘salami-slicing/publishing’).
  • Concurrent or secondary publication is sometimes justifiable, provided certain conditions are met. Examples include: translations or a manuscript that is intended for a different group of readers.
  • Results should be presented clearly, honestly, and without fabrication, falsification or inappropriate data manipulation (including image based manipulation). Authors should adhere to discipline-specific rules for acquiring, selecting and processing data.
  • No data, text, or theories by others are presented as if they were the author’s own (‘plagiarism’). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks (to indicate words taken from another source) are used for verbatim copying of material, and permissions secured for material that is copyrighted.

Important note: the journal may use software to screen for plagiarism.

  • Authors should make sure they have permissions for the use of software, questionnaires/(web) surveys and scales in their studies (if appropriate).
  • Authors should avoid untrue statements about an entity (who can be an individual person or a company) or descriptions of their behavior or actions that could potentially be seen as personal attacks or allegations about that person.
  • Research that may be misapplied to pose a threat to public health or national security should be clearly identified in the manuscript (e.g. dual use of research). Examples include creation of harmful consequences of biological agents or toxins, disruption of immunity of vaccines, unusual hazards in the use of chemicals, weaponization of research/technology (amongst others).
  • Authors are strongly advised to ensure the author group, the Corresponding Author, and the order of authors are all correct at submission. Adding and/or deleting authors during the revision stages is generally not permitted, but in some cases may be warranted. Reasons for changes in authorship should be explained in detail. Please note that changes to authorship cannot be made after acceptance of a manuscript.

*All of the above are guidelines and authors need to make sure to respect third parties rights such as copyright and/or moral rights.

Upon request authors should be prepared to send relevant documentation or data in order to verify the validity of the results presented. This could be in the form of raw data, samples, records, etc. Sensitive information in the form of confidential or proprietary data is excluded.

If there is suspicion of misbehavior or alleged fraud the Journal and/or Publisher will carry out an investigation following COPE guidelines. If, after investigation, there are valid concerns, the author(s) concerned will be contacted under their given e-mail address and given an opportunity to address the issue. Depending on the situation, this may result in the Journal’s and/or Publisher’s implementation of the following measures, including, but not limited to:

  • If the manuscript is still under consideration, it may be rejected and returned to the author.
  • If the article has already been published online, depending on the nature and severity of the infraction:

    - an erratum/correction may be placed with the article

    - an expression of concern may be placed with the article

    - or in severe cases retraction of the article may occur.

The reason will be given in the published erratum/correction, expression of concern or retraction note. Please note that retraction means that the article is maintained on the platform, watermarked “retracted” and the explanation for the retraction is provided in a note linked to the watermarked article.

  • The author’s institution may be informed
  • A notice of suspected transgression of ethical standards in the peer review system may be included as part of the author’s and article’s bibliographic record.

Fundamental errors

Authors have an obligation to correct mistakes once they discover a significant error or inaccuracy in their published article. The author(s) is/are requested to contact the journal and explain in what sense the error is impacting the article. A decision on how to correct the literature will depend on the nature of the error. This may be a correction or retraction. The retraction note should provide transparency which parts of the article are impacted by the error.

Suggesting / excluding reviewers

Authors are welcome to suggest suitable reviewers and/or request the exclusion of certain individuals when they submit their manuscripts. When suggesting reviewers, authors should make sure they are totally independent and not connected to the work in any way. It is strongly recommended to suggest a mix of reviewers from different countries and different institutions. When suggesting reviewers, the Corresponding Author must provide an institutional email address for each suggested reviewer, or, if this is not possible to include other means of verifying the identity such as a link to a personal homepage, a link to the publication record or a researcher or author ID in the submission letter. Please note that the Journal may not use the suggestions, but suggestions are appreciated and may help facilitate the peer review process.

Authorship principles

These guidelines describe authorship principles and good authorship practices to which prospective authors should adhere to.

Authorship clarified

The Journal and Publisher assume all authors agreed with the content and that all gave explicit consent to submit and that they obtained consent from the responsible authorities at the institute/organization where the work has been carried out, before the work is submitted.

The Publisher does not prescribe the kinds of contributions that warrant authorship. It is recommended that authors adhere to the guidelines for authorship that are applicable in their specific research field. In absence of specific guidelines it is recommended to adhere to the following guidelines*:

All authors whose names appear on the submission

1) made substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data; or the creation of new software used in the work;

2) drafted the work or revised it critically for important intellectual content;

3) approved the version to be published; and

4) agree to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

* Based on/adapted from:

ICMJE, Defining the Role of Authors and Contributors,

Transparency in authors’ contributions and responsibilities to promote integrity in scientific publication, McNutt at all, PNAS February 27, 2018

Disclosures and declarations

All authors are requested to include information regarding sources of funding, financial or non-financial interests, study-specific approval by the appropriate ethics committee for research involving humans and/or animals, informed consent if the research involved human participants, and a statement on welfare of animals if the research involved animals (as appropriate).

The decision whether such information should be included is not only dependent on the scope of the journal, but also the scope of the article. Work submitted for publication may have implications for public health or general welfare and in those cases it is the responsibility of all authors to include the appropriate disclosures and declarations.

Data transparency

All authors are requested to make sure that all data and materials as well as software application or custom code support their published claims and comply with field standards. Please note that journals may have individual policies on (sharing) research data in concordance with disciplinary norms and expectations. Please check the Instructions for Authors of the Journal that you are submitting to for specific instructions.

Role of the Corresponding Author

One author is assigned as Corresponding Author and acts on behalf of all co-authors and ensures that questions related to the accuracy or integrity of any part of the work are appropriately addressed.

The Corresponding Author is responsible for the following requirements:

  • ensuring that all listed authors have approved the manuscript before submission, including the names and order of authors;
  • managing all communication between the Journal and all co-authors, before and after publication;*
  • providing transparency on re-use of material and mention any unpublished material (for example manuscripts in press) included in the manuscript in a cover letter to the Editor;
  • making sure disclosures, declarations and transparency on data statements from all authors are included in the manuscript as appropriate (see above).

* The requirement of managing all communication between the journal and all co-authors during submission and proofing may be delegated to a Contact or Submitting Author. In this case please make sure the Corresponding Author is clearly indicated in the manuscript.

Author contributions

Please check the Instructions for Authors of the Journal that you are submitting to for specific instructions regarding contribution statements.

In absence of specific instructions and in research fields where it is possible to describe discrete efforts, the Publisher recommends authors to include contribution statements in the work that specifies the contribution of every author in order to promote transparency. These contributions should be listed at the separate title page.

Examples of such statement(s) are shown below:

• Free text:

All authors contributed to the study conception and design. Material preparation, data collection and analysis were performed by [full name], [full name] and [full name]. The first draft of the manuscript was written by [full name] and all authors commented on previous versions of the manuscript. All authors read and approved the final manuscript.

Example: CRediT taxonomy:

• Conceptualization: [full name], …; Methodology: [full name], …; Formal analysis and investigation: [full name], …; Writing - original draft preparation: [full name, …]; Writing - review and editing: [full name], …; Funding acquisition: [full name], …; Resources: [full name], …; Supervision: [full name],….

For review articles where discrete statements are less applicable a statement should be included who had the idea for the article, who performed the literature search and data analysis, and who drafted and/or critically revised the work.

For articles that are based primarily on the student’s dissertation or thesis, it is recommended that the student is usually listed as principal author:

A Graduate Student’s Guide to Determining Authorship Credit and Authorship Order, APA Science Student Council 2006

Affiliation

The primary affiliation for each author should be the institution where the majority of their work was done. If an author has subsequently moved, the current address may additionally be stated. Addresses will not be updated or changed after publication of the article.

Changes to authorship

Authors are strongly advised to ensure the correct author group, the Corresponding Author, and the order of authors at submission. Changes of authorship by adding or deleting authors, and/or changes in Corresponding Author, and/or changes in the sequence of authors are not accepted after acceptance of a manuscript.

  • Please note that author names will be published exactly as they appear on the accepted submission!

Please make sure that the names of all authors are present and correctly spelled, and that addresses and affiliations are current.

Adding and/or deleting authors at revision stage are generally not permitted, but in some cases it may be warranted. Reasons for these changes in authorship should be explained. Approval of the change during revision is at the discretion of the Editor-in-Chief. Please note that journals may have individual policies on adding and/or deleting authors during revision stage.

Author identification

Authors are recommended to use their ORCID ID when submitting an article for consideration or acquire an ORCID ID via the submission process.

Deceased or incapacitated authors

For cases in which a co-author dies or is incapacitated during the writing, submission, or peer-review process, and the co-authors feel it is appropriate to include the author, co-authors should obtain approval from a (legal) representative which could be a direct relative.

Authorship issues or disputes

In the case of an authorship dispute during peer review or after acceptance and publication, the Journal will not be in a position to investigate or adjudicate. Authors will be asked to resolve the dispute themselves. If they are unable the Journal reserves the right to withdraw a manuscript from the editorial process or in case of a published paper raise the issue with the authors’ institution(s) and abide by its guidelines.

Confidentiality

Authors should treat all communication with the Journal as confidential which includes correspondence with direct representatives from the Journal such as Editors-in-Chief and/or Handling Editors and reviewers’ reports unless explicit consent has been received to share information.

Clinical Trials Registration

For research that started after September 1st, 2015, the journal requires all clinical trials that prospectively assign human subjects to medical interventions, comparison groups, or control groups for the purpose of examining the potential health effects of such interventions, to be registered in one of several free, publicly accessible, non-profit electronically searchable databases such as the one administered by the National Library of Medicine (NLM), which is located at http://www.clinicaltrials.gov.

Submitted manuscripts must include the unique registration number in the abstract as evidence of registration. For details regarding the required minimal registration data set, please go to the International Committee of Medical Journal Editors (ICMJE) site at http://www.icmje.org/#clin_trials.

The journal accepts registration in the following registries:

  • http://www.clinicaltrials.gov/ (Clinical Trials)
  • http://actr.org.au (Australian Clinical Trials Registry)
  • http://isrctn.org (ISRCTN Register)
  • http://www.trialregister.nl/trialreg/index.asp (Netherlands Trial Register)
  • http://www.umin.ac.jp/ctr (UMIN Clinical Trials Registry)

Manuscript Submission

Submission of a manuscript implies: that the work described has not been published before; that it is not under consideration for publication anywhere else; that its publication has been approved by all co-authors, if any, as well as by the responsible authorities – tacitly or explicitly – at the institute where the work has been carried out. The publisher will not be held legally responsible should there be any claims for compensation.

  • Permissions:

Authors wishing to include figures, tables, or text passages that have already been published elsewhere are required to obtain permission from the copyright owner(s) for publication of both the print and online format. (and to include evidence that such permission has been granted when submitting their papers.)

  • Manuscript Submission via Editorial Manager:
Corresponding authors should submit their manuscripts online (http://www.editorialmanager.com/joga/) to facilitate even quicker and more efficient processing. Please note that all correspondence, including proofs for checking and offprint orders, will be sent to the email address of the submitting account via Editorial Manager.

Electronic submission substantially reduces the editorial processing and reviewing time and shortens overall publication time. In case you encounter any difficulties while submitting your manuscript online, click on the Get Help Now icon in the upper right corner of your screen.

  • Author Accounts:

Authors entering the journal’s Editorial Manager site can either create a new account or use an existing one. If you already have an account, use it for all your submissions; you can track their status on the same page. If you have forgotten your user ID and password, please enter your mail address in Password Help. You will then receive an automatic e-mail with your user ID and password.

  • Getting Started:

Once you have logged into your account, Editorial Manager will lead you through the submission process in an orderly, step-by-step process.

Main Documents

The documents should be uploaded in Microsoft Word format (DOC/DOCX).

Manuscripts must be typed double-spaced with wide margins. The title page, abstract, key words, text, acknowledgments and references should begin on separate sheets and follow that order. Incomplete or improperly prepared manuscripts will be returned to authors without review.All manuscripts must be written in English. Authors whose native language is not English should seek the assistance of a colleague who is a native English speaker and is familiar with the field of work.

  • Title Page:

The title page should include:

• The full name(s) of the author(s)

• A concise and informative title

• The affiliation(s) and address(es) of the author(s)

• Short title (not exceeding 30 characters and spaces)

• Word count of the manuscript

  • Abstract:

A structured abstract of not more than 250 words is required if not specified.

It should be divided into the following sections:

• Background

• Methods

• Results

• Conclusions

  • Keywords:

Please provide 3 to 5 keywords which can be used for indexing purposes.

  • Abbreviations:

Standard abbreviations and units should be used. Abbreviations should be defined at first mention and used consistently thereafter.

  • Footnotes:

Footnotes can be used to give additional information, which may include the citation of a reference included in the reference list. They should not consist solely of a reference citation, and they should never include the bibliographic details of a reference.

  • Text:

The body of the article should be divided into four sections:

• Introduction: The Introduction should state the purpose of the work and provide a concise summary of the rationale for the study or observation.

• Methods: In Methods, observational or experimental subjects should be described clearly. Generic names should be used for drug names. If authors so desire, brand names may be inserted in parentheses. The methods should be stated in sufficient detail to allow other researchers to reproduce the results. The statistical methods used should be outlined in enough detail to enable knowledgeable readers with access to the original data to verify the reported results.

• Results: Results should present findings in a logical sequence, with the minimum number of tables and illustrations necessary for summarizing only important observations.

• Discussion: In the Discussion, new and important findings should be discussed with reference to other reported work, and conclusions should be added. Data and other material provided in the Introduction or the Results section should not be repeated in the Discussion section.

  • Acknowledgments:

Acknowledgments of people, grants, funds, etc. should be placed in a separate section before the reference list. The names of funding organizations should be written in full.

All contributors who do not meet the criteria for authorship should be listed in an acknowledgments section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chairperson who provided only general support. Editors should ask corresponding authors to declare whether they had assistance with study design, data collection, data analysis, or manuscript preparation. If such assistance was available, the authors should disclose the identity of the individuals who provided this assistance and the entity that supported it in the published article. Financial and material support should also be acknowledged. Groups of persons who have contributed materially to the paper but whose contributions do not justify authorship may be listed under such headings as "clinical investigators" or "participating investigators," and their function or contribution should be described—for example, "served as scientific advisors," "critically reviewed the study proposal," "collected data," or "provided and cared for study patients."

  • Reference:

- Citation: Reference citations in the text should be identified by numbers in square brackets. Some examples:

1. Negotiation research spans many disciplines [3].

2. This result was later contradicted by Becker and Seligman [5].

3. This effect has been widely studied [1-3, 7].

- Reference list:

The list of references should only include works that are cited in the text and that have been published or accepted for publication. Number references consecutively in the order cited in the text. Accuracy of reference data is the author’s responsibility.

Personal communications and unpublished works should only be mentioned in the text. If such a citation is from someone other than the author(s), a letter should be submitted in which the direct quotation is given with the signature of the person quoted. Unpublished papers accepted elsewhere may be included in the list by designating the journal followed by (In press) in parentheses. Provide inclusive page numbers for all references. Do not use footnotes or endnotes as a substitute for a reference list. In article citations, list the first three authors only and add “et al.”

In principle, only materials published in English can be used as references. When absolutely unavoidable, papers published in a language other than English may be used, but only if they have an English abstract.

Tables

  • All tables are to be numbered using Arabic numerals.
  • Tables should always be cited in text in consecutive numerical order.
  • For each table, please supply a table caption (title) explaining the components of the table.
  • Identify any previously published material by giving the original source in the form of a reference at the end of the table caption.
  • Footnotes to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data) and included beneath the table body.

Artwork and Illustrations Guidelines

Electronic Figure Submission

  • Supply all figures electronically.
  • Indicate what graphics program was used to create the artwork.
  • For vector graphics, the preferred format is EPS; for halftones, please use TIFF format. MSOffice files are also acceptable.
  • Vector graphics containing fonts must have the fonts embedded in the files.
  • Name your figure files with "Fig" and the figure number, e.g., Fig1.eps.

Line Art

  • Definition: Black and white graphic with no shading.
  • Do not use faint lines and/or lettering and check that all lines and lettering within the figures are legible at final size.
  • All lines should be at least 0.1 mm (0.3 pt) wide.
  • Scanned line drawings and line drawings in bitmap format should have a minimum resolution of 1200 dpi.
  • Vector graphics containing fonts must have the fonts embedded in the files.

Halftone Art

  • Definition: Photographs, drawings, or paintings with fine shading, etc.
  • If any magnification is used in the photographs, indicate this by using scale bars within the figures themselves.
  • Halftones should have a minimum resolution of 300 dpi.

Combination Art

  • Definition: a combination of halftone and line art, e.g., halftones containing line drawing, extensive lettering, color diagrams, etc.
  • Combination artwork should have a minimum resolution of 600 dpi.

Color Art

  • Color art is free of charge for online publication.
  • If black and white will be shown in the print version, make sure that the main information will still be visible. Many colors are not distinguishable from one another when converted to black and white. A simple way to check this is to make a xerographic copy to see if the necessary distinctions between the different colors are still apparent.
  • If the figures will be printed in black and white, do not refer to color in the captions.
  • Color illustrations should be submitted as RGB (8 bits per channel).

Figure Lettering

  • To add lettering, it is best to use Helvetica or Arial (sans serif fonts).
  • Keep lettering consistently sized throughout your final-sized artwork, usually about 2–3 mm (8–12 pt).
  • Variance of type size within an illustration should be minimal, e.g., do not use 8-pt type on an axis and 20-pt type for the axis label.
  • Avoid effects such as shading, outline letters, etc.
  • Do not include titles or captions within your illustrations.

Figure Numbering

  • All figures are to be numbered using Arabic numerals.
  • Figures should always be cited in text in consecutive numerical order.
  • Figure parts should be denoted by lowercase letters (a, b, c, etc.).
  • If an appendix appears in your article and it contains one or more figures, continue the consecutive numbering of the main text. Do not number the appendix figures,"A1, A2, A3, etc." Figures in online appendices (Electronic Supplementary Material) should, however, be numbered separately.

Figure Captions

  • Each figure should have a concise caption describing accurately what the figure depicts. Include the captions in the text file of the manuscript, not in the figure file.
  • Figure captions begin with the term Fig. in bold type, followed by the figure number, also in bold type.
  • No punctuation is to be included after the number, nor is any punctuation to be placed at the end of the caption.
  • Identify all elements found in the figure in the figure caption; and use boxes, circles, etc., as coordinate points in graphs.
  • Identify previously published material by giving the original source in the form of a reference citation at the end of the figure caption.

Figure Placement and Size

  • Figures should be submitted separately from the text, if possible.
  • When preparing your figures, size figures to fit in the column width.
  • For large-sized journals the figures should be 84 mm (for double-column text areas), or 174 mm (for single-column text areas) wide and not higher than 234 mm.
  • For small-sized journals, the figures should be 119 mm wide and not higher than 195 mm.

Permissions

If you include figures that have already been published elsewhere, you must obtain permission from the copyright owner(s) for both the print and online format. Please be aware that some publishers do not grant electronic rights for free and that Springer will not be able to refund any costs that may have occurred to receive these permissions. In such cases, material from other sources should be used.

Accessibility

In order to give people of all abilities and disabilities access to the content of your figures, please make sure that

  • All figures have descriptive captions (blind users could then use a text-to-speech software or a text-to-Braille hardware)
  • Patterns are used instead of or in addition to colors for conveying information (colorblind users would then be able to distinguish the visual elements)
  • Any figure lettering has a contrast ratio of at least 4.5:1

Electronic Supplementary Material

Springer accepts electronic multimedia files (animations, movies, audio, etc.) and other supplementary files to be published online along with an article or a book chapter. This feature can add dimension to the author's article, as certain information cannot be printed or is more convenient in electronic form.

Before submitting research datasets as electronic supplementary material, authors should read the journal’s Research data policy. We encourage research data to be archived in data repositories wherever possible.

Submission

  • Supply all supplementary material in standard file formats.
  • Please include in each file the following information: article title, journal name, author names; affiliation and e-mail address of the corresponding author.
  • To accommodate user downloads, please keep in mind that larger-sized files may require very long download times and that some users may experience other problems during downloading.

Audio, Video, and Animations

  • Aspect ratio: 16:9 or 4:3
  • Maximum file size: 25 GB

  • If supplying any supplementary material, the text must make specific mention of the material as a citation, similar to that of figures and tables.
  • Refer to the supplementary files as “Online Resource”, e.g., "... as shown in the animation (Online Resource 3)", “... additional data are given in Online Resource 4”.
  • Name the files consecutively, e.g. “ESM_3.mpg”, “ESM_4.pdf”.

Captions

  • For each supplementary material, please supply a concise caption describing the content of the file.

Processing of supplementary files

  • Electronic supplementary material will be published as received from the author without any conversion, editing, or reformatting.

Accessibility

In order to give people of all abilities and disabilities access to the content of your supplementary files, please make sure that

  • The manuscript contains a descriptive caption for each supplementary material
  • Video files do not contain anything that flashes more than three times per second (so that users prone to seizures caused by such effects are not put at risk)

Other Files (for peer-review only)

If you have other supplementary files for peer-review only, please select “Other Files (for peer-review only)” from the pull-down menu on the system.

PDF Proof before Submission

  • Offprints:

Upon publication the corresponding authors will receive a free eOffprint of their article. Offprints can be ordered by the corresponding author.

  • Proofreading:

Authors are informed by e-mail that a temporary URL has been created from which they can obtain their proofs. The purpose of the proof is to check for typesetting errors and the completeness and accuracy of the text, tables, and figures. Substantial changes in content, e.g., new results, corrected values, title, and authorship, are not allowed without the approval of the Editor. After online publication, further changes can only be made in the form of an Erratum, which will be hyperlinked to the article.

  • Online First:

The article will be published online after receipt of the corrected proofs. This is the official first publication citable with the DOI. After release of the printed version, the article can also be cited by issue and page numbers.
