Recurrent Hematochezia Due to a Rectal Fistula Caused by a Left Internal Iliac Artery Aneurysm.
Article in Cureus, 2025. 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
Arterio-enteric fistulas (AEFs) are a rare cause of gastrointestinal bleeding involving direct communication between an artery and the intestinal tract. The duodenum is the most common fistula site for AEFs, but none of the rectal cases are known. We present the case of an elderly man with hematochezia due to a rectal fistula caused by a left internal iliac artery aneurysm, which was detected on contrast-enhanced computed tomography (CT), showing typical fistula formation and ectopic gas images. This case highlights the importance of considering the occurrence of rare but potentially fatal AEFs in elderly patients with hematochezia and that the timely performance of contrast-enhanced CT is critical for an accurate diagnosis.
