Call for papers: Impact of COVID-19 on clinical trials
29th October 2020
Trials is inviting submission of manuscripts, long and short, including Letters and Commentaries detailing the enforced changes to trial design; trial management; recruitment; consent process; intervention delivery and follow up as a result of the COVID-19 pandemic. We also welcome submission of Updates to protocols previously published in Trials that describe changes made because of the COVID-19 pandemic.
COVID-19 and impact on peer review
23rd March 2020
As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.
Study protocols policy
30th January 2020
Trials are pleased to announce an updated policy for study protocol submissions. We continue to advise that study protocols are submitted to the journal well before recruitment completes, however as of today we will be considering exceptions to this rule. Trials will now consider study protocols submitted before the last piece of data is collected from the last participant if a clear statement outlining this, including an explanation of why it was not possible to submit earlier, is included within the manuscript text. Please confirm the status of your study at submission. For more information, please refer to our submission guidelines.
9th December 2019
Trials is pleased to present a template for a structured study protocol, where all 51 SPIRIT headings and item identifers are included within the manuscript itself. Readers will benefit from the ability to search by item identifier, which are contained within curly brackets.
This is not mandatory and we will continue to consider protocols submitted in other formats against the SPIRIT checklist.
