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

Obscure gastrointestinal bleeding (OGIB) is defined as bleeding not identified by standard endoscopy or colonoscopy and requires advanced diagnostic modalities. Ectopic pancreas is a rare congenital anomaly, usually asymptomatic but occasionally presenting with abdominal pain, obstruction, or gastrointestinal bleeding. We report a 23-year-old female admitted with melena and hemodynamic instability. Initial investigations were inconclusive. Persistent bleeding led to urgent laparotomy, which revealed jejunal nodular lesions. Segmental enterectomy was performed, with favorable recovery. Histology confirmed ectopic pancreatic tissue associated with jejunal angiodysplasia. This rare association highlights diagnostic and therapeutic challenges of OGIB and the importance of surgical intervention in unstable patients.
