Ruptured Brain Arteriovenous Malformation Coexisting With Reversible Cerebral Vasoconstriction Syndrome: A Case Report.
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
Reversible cerebral vasoconstriction syndrome (RCVS) is known to coexist with other vascular lesions; however, the coexistence of a ruptured brain arteriovenous malformation (AVM) and RCVS has not been previously reported. We describe the case of a 48-year-old woman who presented with an acute thunderclap headache followed by left-sided weakness. A noncontrast head CT revealed an acute right frontal intracerebral hemorrhage, extensive subarachnoid hemorrhage, and a right posterior fossa subdural hematoma, a pattern atypical for isolated RCVS. Cerebral angiography demonstrated multifocal vasoconstriction consistent with RCVS. The patient underwent hematoma evacuation, during which a ruptured brain AVM was identified and resected, with histopathologic confirmation. Postoperative cerebral angiography demonstrated no residual AVM. The patient experienced substantial neurological recovery following rehabilitation, with only mild residual left-sided weakness at follow-up. This case underscores the importance of maintaining a high index of suspicion for coexisting vascular lesions in patients with presumed RCVS who present with atypical hemorrhagic patterns.
