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

Gallbladder perforation is a rare and life-threatening event. Accurately diagnosing gallbladder perforation without cholecystitis or gallstones is difficult. The patient was admitted with abdominal pain and was diagnosed with diffuse peritonitis the following day via computed tomography (CT). Laparoscopic findings revealed the accumulation of bile-like ascites and a thinned and soft gallbladder with slight leakage of bile juice from a pinhole perforation. Laparoscopic cholecystectomy and peritoneal lavage were then performed. In the present case, it was difficult to diagnose gallbladder perforation because of the lack of cholecystitis and gallstones in the CT findings. If preoperative CT shows an acute abdomen with peritoneal effusion, especially accumulated around the gallbladder, then gallbladder perforation may be considered as a primary lesion.
