Clinical trial registration facilitates identification, tracking, and assessment of clinical trials and limits publication bias caused by the selective reporting of trial results.1 Inclusion of trial registration numbers in conference abstracts, as recommended by the Consolidated Standards of Reporting Trials (CONSORT) guidelines for abstracts2 is particularly important because many conference presentations of trials remain unpublished.3 In the present study, we reviewed abstracts presented at 8 major medical and surgical conferences held in 2017 to assess the extent to which conference abstracts reporting randomized clinical trial (RCT) results cite trial registration numbers and conform to other key CONSORT guidelines.
