Ruptured Aneurysm in Complete Duplication of the Posterior Cerebral Artery: Successful Treatment With Endovascular Coiling.
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
The fetal posterior cerebral artery (FPCA) variant is rare, and among these, complete duplication of the posterior cerebral artery (PCA) represents the rarest form. In this case report, we describe a 39-year-old woman with an aneurysm arising from complete duplication of the PCA. The aneurysm was successfully occluded while preserving FPCA patency using endovascular coiling with the double-microcatheter technique, and no recurrence of the aneurysm was observed on brain magnetic resonance angiography (MRA) at six-month follow-up. To the best of our knowledge, this is the first reported case of an aneurysm arising from complete duplication of the PCA that was successfully treated by endovascular coiling. We highlight the anatomical characteristics of complete duplication of the PCA, the utility of multimodal imaging in identifying FPCA variant, and the need to preserve the FPCA during aneurysm treatment to prevent PCA territory infarction.
