Multiple arteriovenous malformations due to liver failure: An unusual etiology.
Article in Journal of vascular surgery cases and innovative techniques, 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
Arteriovenous malformations (AVMs) are rare vascular anomalies, predominantly congenital and intracranial. We report a unique case of multiple extracranial acquired AVM in a 44-year-old man with ethanol-related decompensated chronic liver disease presenting with severe gingival hemorrhage. Angiography showed focal microarteriovenous shunting with early venous drainage in the absence of a mature, compact nidus involving the facial and lingual arterial systems, which was successfully treated with endovascular embolization. In the absence of earlier vascular pathology, an acquired etiology is suspected. Cirrhosis-associated angiogenic and inflammatory dysregulation may contribute to de novo AVM formation, and reported regression following liver transplantation suggests a potentially reversible, hepatic-driven mechanism.
