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
Anomalous pancreaticobiliary ductal union (APBDU) represents a congenital anomaly predisposing patients to biliary dilatation. This aberrant architecture facilitates the intermingling of pancreatic and biliary fluids, thereby elevating susceptibility to cholelithiasis and malignancies of the biliary tract. While radical cholangiojejunostomy constitutes the standard therapeutic intervention, it frequently fails to rectify the underlying APBDU. Retention of an excessively elongated common bile duct (CBD) remnant can generate a blind loop, precipitating stone formation within the common channel years following the procedure. Such delayed manifestations in adult populations remain scarcely documented. We herein present a case involving a patient with P-B-type APBDU who exhibited symptoms two decades post-cholangiojejunostomy. Radiological assessment identified a CBD stump measuring approximately 2.5 cm alongside a substantial pancreatic calculus. This instance underscores the compounding effects of uncorrected APBDU morphology and a surgically induced, overly extensive blind loop, extending beyond the conventional paradigm of pancreaticobiliary reflux. Management was achieved exclusively via endoscopic sphincterotomy coupled with accessory cholangioscopy-assisted lithotomy. This report bridges a critical knowledge gap regarding extremely late-onset pancreatic duct stones within the common channel subsequent to cholangiojejunostomy. Furthermore, we underscore the imperative for precise preoperative evaluation of biliary anatomy and stringent intraoperative regulation of stump length.
