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
backgroundEarly laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreatography (ERCP) is recommended for patients with choledocholithiasis to reduce the risk of recurrent biliary events (RBE). However, in clinical practice early surgery is not always feasible. The role of biliary stenting as a bridging strategy before delayed cholecystectomy remains insufficiently studied. This study evaluated outcomes of delayed cholecystectomy after ERCP with biliary stent placement compared with early surgery in a stented cohort.
methodsWe conducted a retrospective single-center study including patients who underwent ERCP with biliary stent placement followed by early cholecystectomy (≤ 14 days; eCCY) or delayed elective cholecystectomy (> 14 days; dCCY). The primary endpoint was the occurrence of RBE. Inverse probability of treatment weighting (IPTW) and sensitivity analysis were performed to address baseline imbalances. Multivariable logistic regression was performed to identify independent predictors of RBE. Incidence rates per person-time were calculated to account for differences in exposure time. Kaplan-Meier analysis assessed the temporal distribution of events. A sensitivity analysis was conducted excluding patients with acute cholecystitis at presentation.
resultsA total of 338 patients were included (85 eCCY, 253 dCCY). Overall RBE occurred in 16.9% of patients, with no significant difference between groups (20.0 vs. 15.8%, p = 0.372). Timing of cholecystectomy was not independently associated with RBE (odds ratio 1.40, 95% confidence interval 0.71-2.76, p = 0.340). The incidence rate was 3.04 per 100 person-days in the eCCY group and 0.22 in the dCCY group, reflecting non-random treatment allocation. Intraoperative and postoperative outcomes were comparable. However, patients requiring urgent surgery due to RBE demonstrated increased operative complexity. The IPTW adjustment and sensitivity analysis confirmed all primary findings.
conclusionsIn selected patients undergoing ERCP with biliary stent placement, delayed cholecystectomy was safe and feasible and was not associated with worse perioperative outcomes compared with early surgery. RBE occurred predominantly in the early post-ERCP period, but overall risk was not increased by delayed surgery. Patients requiring urgent surgery represent a higher-risk subgroup.
