A Rare Cause of Upper Gastrointestinal Bleeding: Superior Mesenteric 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
Superior mesenteric artery (SMA) aneurysms are a rare cause of gastrointestinal (GI) bleeding that is usually underdiagnosed. These conditions can lead to severe complications, making prompt treatment essential. We report a case of a 87-year-old female patient admitted for intense pain in the abdominal area. After a 24-hour hospital stay, she had an episode of hematochezia, hematemesis, and intense epigastric pain. Upper GI endoscopy revealed a foreign body in the duodenum, which was removed. The bleeding and the hemodynamic instability were persistent even after the removal of the foreign body. A CT angiography revealed an aneurysm in the SMA with active contrast extravasation. The patient underwent endovascular treatment with coil embolization, achieving complete hemodynamic stabilization without complications. GI bleeding from an aneurysm in the SMA is an unusual but critical entity with high mortality (40-60%); thus, rupture of the SMA aneurysm should always be considered in the differential diagnosis in cases with persistent GI bleeding. Regarding the hemodynamic stability of the patient or the patient's overall clinical condition, the available treatment options include endoscopic interventions or open surgery. Endovascular treatment offers a safe and effective alternative to open surgery, with favorable outcomes. Prompt diagnosis and, most of the time, endovascular embolization are crucial for successful management of SMA aneurysm-related upper GI bleeding.
