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

Choledochal cysts are uncommon congenital bile duct dilatations, and adult presentation is often complicated by obstruction, cholangitis, pancreatitis, stones, or malignant transformation. We report a 53-year-old woman with obstructive jaundice and severe hepatobiliary injury. Ultrasonography and contrast-enhanced computed tomography showed a giant extrahepatic bile duct cyst measuring ~15-16 cm, marked intrahepatic duct dilatation, gallbladder distension, and enhancing biliary walls without a visible obstructing stone, consistent with a Todani type IVa choledochal cyst complicated by cholangitis. Ultrasound-guided percutaneous biliary drainage was performed, with marked biochemical improvement. Definitive open surgery included cholecystectomy, complete extrahepatic cyst excision, and Roux-en-Y hepaticojejunostomy. This case highlights a surgical pitfall in which a giant bile duct cyst mimics gallbladder hydrops and supports staged decompression before definitive biliary reconstruction when cholangitis is present.
