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
BackgroundIntracranial vessel perforation is a rare but life-threatening complication during endovascular neurointerventions. Despite several described bail-out strategies, there is no consensus on the most effective approach for rapid hemorrhage control. This study aimed to systematically compare common endovascular rescue techniques in a standardized experimental setting.MethodsPatient-specific, 3D-printed vascular models of the anterior circulation were used to simulate standardized vessel perforations at two anatomical sites and three perforation sizes. The impact of the anterior communicating artery (AComA) crossflow was assessed. Proximal balloon guiding catheter inflation, local compliant balloon inflation, temporary coil deployment, and distal intermediate catheter insertion were evaluated against a non-intervention control. The primary outcome was the time it took for 50 ml of fluid extravasation to accumulate.ResultsAs expected, extravasation time inversely correlated with perforation size (
