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

Cholecystectomy is associated with a variety of complications. Imaging plays a pivotal role in diagnosing these complications, but some imaging findings are poorly understood and unexplored. Here, we present a 59-year-old woman with a mass-like solid-cystic lesion at the cholecystectomy bed after 12 years of surgery. The lesion was hypoechoic in ultrasound, hypodense in CT scan, and had low T2 and intermediate T1 signal intensity and no enhancement in MRI, which was not consistent with the imaging characteristics of known complications. Histopathological evaluation revealed foreign body fragments and fibrin materials within the lesion. We conclude that radiologists should be familiar with these findings to avoid unnecessary interventions and misdiagnosis.
