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 34-year-old man presented to the emergency department with a chief complaint of epigastric pain. Endoscopic ultrasound detected a 5 mm stone in the common bile duct. After endoscopic sphincterotomy, the black stones and debris were removed with balloon catheter. Abdominal ultrasonography detected no gallbladder stones; hence, the patient was followed up. However, 3 months later, the patient again developed acute cholangitis caused by common bile duct stones and underwent endoscopic stone removal. Cholangiography under balloon occlusion revealed a left hepatic duct diverticulum with an internal defect. Intraductal ultrasonography showed a hyperechoic lesion with acoustic shadow in the diverticulum, suggesting a stone or debris. Therefore, the patient was considered to have had repeated acute cholangitis because of the presence of falling diverticular stones. The patient underwent left hemihepatectomy plus segmentectomy 1 and cholecystectomy. Histopathologically, it was a true diverticulum without internal epithelial atypia. Many debris were seen in the diverticulum. Gallbladder stones were not observed. Eventually, the patient was discharged from the hospital with no postoperative complications and no recurrence of cholangitis after 20 months.
