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
Background and study aims: With widespread application of pancreatic stent in managing pancreatic diseases and preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, incidence of stent-related complications such as proximal migration has substantially increased. This study aimed to provide strategic insights for retrieving proximally migrated pancreatic stents by analyzing a large endoscopy center experience and synthesizing novel techniques. Patients and methods: A retrospective analysis was conducted over 10 years, including 43 cases of proximally migrated pancreatic stent among 32,537 ERCP procedures (2014-2024). Patient demographics, stent features, and procedure details were assessed. Literature on advanced retrieval techniques was reviewed. Results: Most patients (67.4%) were asymptomatic; epigastric discomfort occurred in 32.6%. Endoscopic retrieval was successful in 81.4% of cases (35/43), with 58.1% (25/43) achieved using a single accessory. Median operation duration was 35 minutes (interquartile range 24-59). Pancreatic duct pre-dilation significantly shortened the procedure (31 ± 9 vs. 47 ± 13 minutes, Conclusions: Endoscopic retrieval is safe and effective for proximal pancreatic stent migration. Success optimization requires careful preoperative evaluation, ductal preparation, and adoption of advanced techniques for difficult cases. The DTRS concept provides a valuable framework for clinical decision-making when standard retrieval fails.
