  • High visibility of your research - over 2 million accesses annually
  • Considers methodology research and aims to build an evidence base to inform future trial design 
  • Supports transparent reporting of trials via protocols, statistical analysis plans and results

Trials is dedicated to improving the design, conduct and reporting of randomised controlled trials in health. Edited by an internationally renowned Editorial Board, we consider articles assessing aspects of the performance or findings of trials, including general trial methodology, commentaries, primary research and study protocols. With over 2 million accesses annually, we are committed to reducing waste in research by experimenting with, and refining, innovative approaches to improving communication about trials.

    Aims and Scope


    Trials encompasses all aspects of the performance and findings of randomized controlled trials in health. We publish articles on general trial methodology and research into trial processes, as well as study protocols and statistical analysis plans for randomised controlled trials, commentaries and traditional results papers - regardless of outcome or significance of findings.

    Our aim is to promote transparency in the reporting of randomised trials and build an evidence base that will help inform the design and reporting of future trials. Within this remit, we consider articles or study protocols assessing aspects of the design, conduct or reporting of trials, as well as assessment and evaluation of lessons learnt from past trials, including those that were prematurely ended. We advocate for the collective success for trials and the importance of linking publications together (the thread of evidence).

    To facilitate complete and transparency reporting of research, Trials does not ask authors to adhere to strict word limits. We request that authors provide the detail required to make the research replicable. We ask that authors communicate not only all outcome measures, as well as varying analyses and interpretations, but also in-depth descriptions of what they did and what they learnt. This sharing of direct experience is fundamental to improving the quality and conduct of trials worldwide.

    Trials aims to experiment with, and refine, innovative approaches to improving communication about randomized controlled trials. We are keen to move beyond publishing traditional trial results articles (although these are included), and we believe this journal represents an exciting opportunity to advance the science and reporting of trials.
