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: Stent-assisted coiling (SAC) is an established option for wide-neck intracranial aneurysms. However, ischemic complications such as in-stent thrombosis or stenosis remain, particularly when stents are deployed in small-caliber vessels. The Neuroform Atlas is generally recommended for parent vessels ≥2 mm, and data on its use in small-caliber arteries arising from the posterior cerebral artery (PCA), including the circumflex branch, are limited. Case Description: A 51-year-old woman with autosomal dominant polycystic kidney disease and prior renal transplantation presented with sudden severe headache and vomiting. Magnetic resonance imaging (MRI) showed no subarachnoid hemorrhage, while magnetic resonance angiography revealed a wide-neck basilar artery (BA) tip aneurysm suggestive of impending rupture. Emergent SAC was performed after dual antiplatelet therapy with aspirin and prasugrel. A microcatheter was advanced into a branch arising from the left PCA P1 segment, initially presumed to be the P2 segment. After coil placement revealed neck instability, a 3.0 × 15 mm Neuroform Atlas was deployed from the presumed P2 segment toward the BA. Cone-beam computed tomography demonstrated that approximately 5 mm of the distal stent had unintentionally extended into a PCA circumflex branch. Because antegrade flow was preserved, conservative management was chosen. Postprocedural MRI showed no infarction. One-year angiography demonstrated complete aneurysm occlusion and sustained circumflex branch patency. Conclusion: Long-term patency without ischemic complications was achieved despite unintentional stent deployment in a circumflex branch. This case underscores the importance of appropriate antithrombotic therapy and highlights the need for constant intraoperative awareness of the potential for unintended device deployment into perforating arteries during endovascular treatment.
