What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLaparoscopic cholecystectomy (LC) is a common surgical procedure and a key component of surgical training. However, balancing resident education with patient safety remains a challenge. Despite its common use in hepatopancreatobiliary surgery, the role of the reusable bipolar clamp (BiClamp) in LC has not been fully evaluated. This study aims to assess the technical aspects, safety, and learning curve associated with a standardized LC technique using the BiClamp, performed by surgical residents.
methodsA total of 780 consecutive LCs performed by seven surgical residents from 2018 to 2024 were retrospectively analyzed. Only residents without prior LC experience were included. All relevant perioperative outcomes were evaluated. Learning curves were assessed using (risk-adjusted) cumulative sum analyses based on operation time and suboptimal performance, defined as extended operation time, intraoperative complications, or conversion to open surgery.
resultsNo intraoperative biliary or vascular injuries occurred. Conversion to open surgery was necessary in only 0.3% of cases. The overall mean operation time was 57.2 ± 16.5 min and suboptimal performance was observed in 10.6% of cases. The learning phase lasted 8-18 procedures, with proficiency reached after 21-97 cases. Risk-adjusted cumulative sum analyses confirmed performance improvements despite increasing case complexity.
conclusionLC using the BiClamp is a safe and effective technique for surgical training, with a relatively short learning curve. These findings support its integration into standardized LC protocols for residents, though further multicenter validation is warranted.
