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

backgroundInferior mesenteric arteriovenous fistula (IMAVF) is an extremely rare condition characterized by abnormal communication between the inferior mesenteric artery and vein. IMAVF often mimics ischemic bowel disease and ulcerative colitis (UC), leading to diagnostic challenges and treatment failures. CASE SUMMARY: Three consecutive cases presented with non-specific symptoms including perianal pain and bloody diarrhea were reported. Initial diagnosis included acute severe UC and ischemic colitis. Pathology suggested ischemic changes, and with further contrast-enhanced computed tomography together with digital subtraction angiography which confirmed the diagnosis of IMAVF. All three cases were treated by vascular embolization, and symptoms improved rapidly following treatment.

conclusionWe presented the largest single center IMAVF series with detailed clinical characteristics, facilitating early diagnosis for similar cases in the future.
