RT Journal Article SR Electronic T1 Writing up your clinical trial report for a scientific journal: the REPORT trial guide for effective and transparent research reporting without spin JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 683 OP 691 DO 10.1136/bjsports-2021-105058 VO 56 IS 12 A1 Bandholm, Thomas A1 Thorborg, Kristian A1 Ardern, Clare L A1 Christensen, Robin A1 Henriksen, Marius YR 2022 UL http://bjsm.bmj.com/content/56/12/683.abstract AB The REPORT guide is a ‘How to’ guide to help you report your clinical research in an effective and transparent way. It is intended to supplement established first choice reporting tools, such as Consolidated Standards of Reporting Trials (CONSORT), by adding tacit knowledge (ie, learnt, informal or implicit knowledge) about reporting topics that we have struggled with as authors or see others struggle with as journal reviewers or editors. We focus on the randomised controlled trial, but the guide also applies to other study designs. Topics included in the REPORT guide cover reporting checklists, trial report structure, choice of title, writing style, trial registry and reporting consistency, spin or reporting bias, transparent data presentation (figures), open access considerations, data sharing and more.
