Ultrafast rebleeding pediatric brain arteriovenous malformation: a case report.
Article in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 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
Brain arteriovenous malformation (bAVM) is the leading cause of intracranial haemorrhage in children, often resulting in severe morbidity and mortality. While both early and delayed interventions for ruptured bAVMs have advantages, the optimal timing remains controversial. We report an 11-year-old girl with a Spetzler-Martin grade III bAVM presenting with a distal flow-related aneurysm and mild altered consciousness. Six hours after the initial hemorrhage, she developed ultrafast rebleeding, necessitating emergency hematoma evacuation and subsequent staged embolization and resection. Despite total AVM removal, she suffered right hemiparalysis. This case highlights the potential for ultrafast rebleeding in pediatric bAVMs, particularly when distal flow-related aneurysms and altered consciousness are present. Early recognition and timely surgical intervention, including hemorrhage evacuation, should be considered to reduce the risk of catastrophic rebleeding and improve outcomes in this vulnerable population.
