Registration quality and key surgical safety outcome coverage of ChiCTR gallstone minimally invasive intervention trials: derived data and recalculation code

The study assessed registration timing, sufficiency of primary-outcome specification, and registration coverage of key surgical safety outcomes among interventional studies of minimally invasive surgery and integrated endoscopic-surgical pathways for gallstone-related diseases in China.

Data were current to 19 July 2026. Twenty-nine prespecified search strings yielded 1,481 term-level hits; after de-duplication, 408 records entered screening, and the strict registry-source primary cohort comprised 38 independent trials, with three post-lock eligibility sensitivity scenarios of 39, 40 and 41 trials.The dataset contains trial-level derived fields, 296 classified outcomes, 82 classified interventions, four-scenario membership flags, post hoc specific-safety flags, 7 registration-publication pairs, the complete search strategy and 408 screening dispositions, together with a recalculation script that depends only on the Python standard library and fully reproduces all proportions, Wilson 95% confidence intervals and sensitivity analyses reported in the article.The dataset contains no patient-level data, no identifiable personal information, no mirrored registry page text and no article full text.
