Analysis of Intraoperative Complications and Outcomes Associated With Obesity During Elective Laparoscopic Cholecystectomy.
Article in World journal of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAs obesity becomes more common, understanding its risks in routine operations is increasingly important. This study assessed the impact of obesity on intraoperative complications during elective laparoscopic cholecystectomy.
methodsRetrospective data on elective laparoscopic cholecystectomies across a single metropolitan health network were collected from July 2021-June 2023. Patients were stratified into WHO-defined obesity classes. Intraoperative complication (measured by ClassIntra classification), intraoperative and postoperative outcomes were compared.
resultsThere were 713 patients included. Intraoperative complications graded as ClassIntra 1 and 2 were 11.0% and 6.1% for non-overweight patients and rose to 35.3% and 13.2% respectively for class III obesity (p < 0.001). Increasing obesity class was independently associated with higher intraoperative complication severity, with a 2.59-fold increase in the odds of a more severe complication category per class increase (p < 0.001). Obesity was associated with increased operative duration (p = 0.006) but did not increase the risk of postoperative morbidity (p = 0.88).
conclusionObesity significantly increases the risks of intraoperative complications in patients undergoing elective cholecystectomy, as measured by the ClassIntra classification, and contributes to increased operative duration. Despite this, postoperative morbidity remains low with no significant difference in length of stay, complications or readmissions across obesity classes.
