A novel classification for posterior communicating artery aneurysms in the presence of fetal posterior cerebral artery: A registry-based study.

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
Background and objectivesFetal posterior cerebral artery (fPCA) is a common anatomical variant where the P1 segment is hypoplastic or absent, and the posterior communicating artery supplies the posterior cerebral artery (PCA) territory. Aneurysms in this setting often form at the internal carotid artery (ICA)-posterior communicating artery junction and are poorly defined. This study introduces a novel classification to address the fPCA variant, treatment challenges, and outcomes.MethodsThis registry-based study included fPCA aneurysms treated endovascularly at the Medical University of South Carolina (2013-2024). Aneurysms are classified into type-1 (shared neck with ICA and fPCA), type-2 (neck arises from ICA, and fPCA originates from the aneurysm), and type-3 (neck originates entirely from fPCA). Aneurysm type, treatment strategy, and outcomes were compared.ResultsForty fPCAs, consisting of 20 type-1, 15 type-2, and five type-3 aneurysms, were analyzed. For type-1 aneurysms, recurrence on admission was higher (40%,
