Evaluating the Impact of Assessing During Peer Review the CONSORT Checklist Submitted by Authors

Randomised trials are considered the gold standard in medical research. The CONSORT (Consolidated Standards of Reporting Trials) Statement aims to improve the quality of reporting of randomised trials. Without transparent reporting, readers cannot judge the reliability and validity of trial findings, and therefore these findings cannot inform clinical practice.

In recent years, different stakeholders have acted to boost the completeness of reporting of the published randomised trials, and therefore their transparency and reproducibility. In a recently completed scoping review, the investigators identified and classified 31 interventions to improve adherence to reporting guidelines. This review revealed that it is primarily journals that have taken most efforts to improve the completeness of reporting of randomised trials - although most of their actions have been shown not to have the desired effect.

One of the most popular strategies used by journals to improve adherence to CONSORT requires authors to submit a populated checklist together with their manuscript indicating page numbers corresponding to each item. However, journals usually lack further actions throughout the editorial process to ensure that the corresponding information to each item is reported in the randomised trial manuscript. This has been hypothesized to be one of the reasons why this editorial strategy has not achieved optimal results.

In an effort to take full advantage of requiring the submission of populated checklists, the investigators intend to evaluate in a real editorial context whether assessing during peer review the consistency between the submitted CONSORT checklist and the information reported in the manuscripts of randomised trials, as well as to provide feedback to authors on the inconsistencies found, improves the completeness of reporting of published trials.

Inclusion criteria

Manuscripts will be eligible if:

• They have been submitted to BMJ Open,
• They are original research submissions reporting the results of a randomised trial, and
• They have passed the first editorial filters and have been subsequently sent out for peer review.
• Authors of these manuscripts have provided a completed CONSORT checklist.

According to the official CONSORT extensions, the investigators will also consider other study designs (cluster, non-inferiority and equivalence, pragmatic, N-of-1 trials, Pilot and feasibility, and within person trials), and different intervention types (Herbal, non-pharmacologic, acupuncture and Chinese herbal medicine formulas) in all areas of clinical specialty.

Exclusion criteria

• Protocols of randomised trials
• Secondary trial analysis studies
