Abstract

fetched live from OpenAlex

Objective To assess registration and reporting details of randomized controlled trials (RCTs) published from 2011 to 2016 across four obesity journals. Methods All issues from four leading obesity journals were searched systematically for RCTs from January 2011 to June 2016. Data on registration status were extracted from manuscripts, online trial registries, and a trial database; corresponding authors were contacted for registration details, when necessary. The methodological reporting of RCTs was assessed on specific criteria from the Consolidated Standards of Reporting Trials. Results A total of 223 RCTs were reviewed. Three‐quarters ( n = 170) were registered publicly; 94 (55.3%) reported registration details in the manuscript, and 82 (48.2%) were registered prospectively. Newer RCTs were more likely to be registered prospectively than older RCTs (2014‐2016: 57.3% vs. 2011‐2013: 39.2%; c 2 = 5.5, P = 0.02). Assessment on the Consolidated Standards of Reporting Trials demonstrated that less than half of all studies reported data collection dates ( n = 108; 48.4%) or included “randomized trial” in the title ( n = 89; 39.9%). Conclusions The methodological reporting of RCTs published in obesity journals is suboptimal, despite current guidelines and policies. To complement existing standards, editorial boards should incorporate mandatory fields within the online manuscript submission process to enhance the quality, transparency, and comprehensiveness of reporting RCTs in obesity journals.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
