Surgical risk calculator development for postoperative outcomes after laparoscopic cholecystectomy: a multicenter prospective cohort study.
Article in Annals of surgical treatment and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: Laparoscopic cholecystectomy is the standard surgical procedure for benign gallbladder disease. However, the analysis of risk factors for complications, including serious complications such as bile duct injury (BDI), has been largely overlooked. This study aimed to collect standardized prospective data from multiple centers and to develop a predictive model for laparoscopic cholecystectomy complications. Methods: This study included 2,514 patients who underwent laparoscopic cholecystectomy for benign gallbladder disease at 18 academic institutes in Korea. Fifty-six preoperative and intraoperative variables were analyzed as risk factors for adverse postoperative outcomes, including overall complications. A surgical risk calculator was developed using a multivariate logistic regression analysis. Results: Of the 2,514 patients, 62 (2.5%) experienced surgery-related complications, including BDI in 17 (0.7%). Various factors such as sex, age, smoking, emergency operation, hypertension, diabetes mellitus, chronic obstructive pulmonary disease, preoperative endoscopic common bile duct stone removal, therapeutic antibiotics usage, American Society of Anesthesiologists physical status classification, and acute cholecystitis were found to be associated with postoperative adverse outcomes. Based on these variables, a surgical risk calculator was developed for overall complications, systemic complications, surgery-related complications, BDI, and delayed discharge, with the area under the curve values of 0.733, 0.775, 0.697, 0.857, and 0.833, respectively. Conclusion: This study developed a surgical risk calculator using standardized variables from a multi-institutional prospective database to predict adverse outcomes after laparoscopic cholecystectomy. This tool can be used for risk stratification prior to cholecystectomy.
