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

The arc of Bühler (AOB) is a rare embryonic anastomosis between the celiac artery and the superior mesenteric artery, which may become a crucial collateral pathway in cases of celiac axis stenosis. We report a challenging case of a 70-year-old woman presenting with hemorrhagic shock owing to a bleeding branch of an aneurysmal and highly tortuous AOB, with median arcuate ligament compression of the celiac trunk. Endovascular treatment was performed successfully by selective embolization of the bleeding branch with the sacrifice of the AOB using a Penumbra Occlusion Device and packing coils, preserving celiac-mesenteric circulation via the pancreaticoduodenal arcade. This case highlights the importance of recognizing vascular variants and adapting embolization strategies to complex anatomy in emergency settings, reinforcing the pivotal role of interventional radiology in managing visceral aneurysms and acute abdominal hemorrhage.
