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
backgroundEndoscopic retrograde cholangiopancreatography involves selective bile duct cannulation, which is often challenging and associated with complications. In difficult cannulation cases, early precutting is frequently used. However, its efficacy and optimal indications require further evaluation.
aimTo evaluate the efficacy and safety of early precut (EP) in difficult bile duct cannulation.
methodsThis retrospective analysis of endoscopic retrograde cholangiopancreatography procedures was performed for bile duct cannulation in patients with naive papillae who required advanced cannulation techniques (ACTs). These patients were admitted between April 2020 and March 2024 and were analyzed for risk factors, success rates, and complications. Outcomes were compared between the EP group and the conventional other ACTs group, with a focus on cases with oral protrusion large (oral protrusion-L).
resultsThe need for ACTs was identified as an independent risk factor for complications [odds ratio (OR) = 5.4; 95% confidence interval: 1.887-15.53]. Malignant biliary strictures (OR = 2.58) and oral protrusion-L (OR = 2.77) were also identified as independent risk factors for requiring ACTs. The EP group had a significantly higher second-line cannulation success rate (97.9%
conclusionThis study provides compelling evidence that EP is a viable alternative and a superior strategy in cases requiring ACTs, particularly oral protrusion-L.
