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 cystic duct entering the right hepatic duct is a rare biliary anatomical variation that increases the risk of bile duct injury during laparoscopic cholecystectomy. We report a 42-year-old woman with cholelithiasis and gallbladder adenomyomatosis in whom preoperative magnetic resonance cholangiopancreatography demonstrated the cystic duct entering the right hepatic duct. During laparoscopic cholecystectomy, the cystic duct ran cranially toward the hepatic hilum and appeared to continue beneath the serosa of the hepatoduodenal ligament into the right hepatic duct. Intraoperative cholangiography confirmed the anomalous anatomy, and the operation was completed safely. The postoperative course was uneventful. A cranially coursing cystic duct and subserosal continuity toward the hepatic hilum may serve as practical intraoperative warning signs of this rare anomaly and should prompt confirmation of biliary anatomy before duct division.
