Pterional craniotomy for occlusion of a basal temporal arteriovenous fistula.
Article in Neurosurgical focus: Video, 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
Atypical arteriovenous fistulas (AVFs) lack the parenchymal nidus observed in arteriovenous malformations (AVMs) and are not dural-based lesions supplied by meningeal arteries, unlike true dural AVFs. Atypical AVFs are parenchymally based with a nondural arterial supply. This video presents a man in his 50s with a remote carotid takedown for flow reduction of a described temporal AVM. Imaging showed a basal temporal AVF supplied by middle cerebral artery branches, coalescence of arterial feeders onto a large venous varix, and no intervening nidus. Dearterialization of the venous varix eliminated the shunting lesion. Atypical AVFs are often misdiagnosed but can be cured with microsurgical interruption.
