1 · What the graph read from it

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.

2 · The registry

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

A 92-year-old woman underwent endoscopic retrograde cholangiopancreatography (ERCP) for acute cholecystitis and bile duct stones. A cascade stomach caused significant difficulty in duodenal intubation, despite multiple standard maneuvers. As a large-diameter overtube was unavailable, forceps were inserted through the accessory channel to increase endoscope rigidity. This technique minimized scope looping and enabled duodenal access within 2 minutes. Biliary cannulation, sphincterotomy, and drainage were completed successfully. The same method was used in a subsequent ERCP with similar success. This case demonstrates that forceps-assisted rigidity reinforcement is a simple, effective, and equipment-free option for managing duodenal intubation difficulties during ERCP.
