Preoperative prediction model for critical view of safety achievement in laparoscopic cholecystectomy: a retrospective cohort study.
Article in Surgical endoscopy, 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
backgroundWe developed and validated a preoperative model to predict the difficulty in achieving the critical view of safety (CVS) during laparoscopic cholecystectomy (LC).
methodsPatients who underwent LC with preoperative computed tomography (CT) and magnetic resonance cholangiopancreatography between January 2015 and December 2023 were retrospectively analyzed and randomly assigned to derivation and validation cohorts (8:2). Surgical difficulty was defined as failure to achieve CVS. Logistic regression analysis was used to identify independent predictors. Model performance was evaluated using the area under the receiver operating characteristic curve and Brier score.
resultsIndependent preoperative risk factors included age ≥ 65 years, American Society of Anesthesiologists physical status ≥ 3, preoperative endoscopic gallbladder drainage or stenting, CT attenuation of the CVS window ≥ - 26 HU, and common bile duct disruption on magnetic resonance cholangiopancreatography (all p < 0.05). The prediction score (0-13) demonstrated an area under the receiver operating characteristic curve of 0.732 (95% confidence interval 0.528-0.936) in the validation cohort. Risk stratification identified low-, moderate-, and high-risk groups with increasing rates of failure to achieve CVS.
conclusionsThis preoperative imaging-based scoring system may help predict CVS failure in LC and guide surgical decision-making.
