Discovery and management of arteriovenous malformation with jejunal diverticulum: elusive gastrointestinal bleed.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Gastrointestinal (GI) bleeds can pose significant life-threatening situations if not identified promptly, progressing to hemorrhagic shock. We discuss the case of a 60-year-old man presenting with an elusive GI bleed. Esophagogastroduodenoscopy, colonoscopy, Meckel's scan, and computed tomographic angiography were performed, which yielded no active bleed despite active hemorrhage. As a result, double-balloon computed tomography enterography was performed, demonstrating jejunal diverticula with angiodysplasia and arteriovenous malformations (AVMs), suspected to be the source of the elusive GI bleed. Clips were attempted at the sites of visible AVMs, but were unsuccessful. The diverticula were tattooed with a plan for an exploratory laparotomy for definitive treatment. The patient was ultimately discharged with no signs of active bleeding and an uncomplicated recovery. This case highlights the multifactorial management of a massive GI bleed with no identifiable source of bleeding upon admission, progressing into hemorrhagic shock.
