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
BackgroundThe supreme anterior connecting artery (SAConnA) is an exceedingly rare anatomical variant. This artery may interconnect bilateral anterior cerebral arteries (ACAs), yet its existence and clinical implications are scarcely discussed in the literature.Case descriptionA 60-year-old man with no significant past medical or family history presented to our emergency department. He exhibited right homonymous hemianopsia and Gerstmann's syndrome. Cranial computed tomography indicated a left parietal lobar hemorrhage, and digital subtraction angiography revealed a flow-related aneurysm in the anterior communicating artery, with the arteriovenous malformation (AVM) receiving blood supply from the anterior, middle, and posterior cerebral arteries. Notably, the angiography also disclosed the presence of a SAConnA. We adopted a treatment approach of staged embolizations followed by resection. During the second session, the SAConnA was utilized for the embolization of feeding arteries within the ACA system.ConclusionsThis case demonstrates that SAConnA can be associated with AVMs and can serve as an access route during AVM embolization. SAConnA may be a remnant artery interconnecting bilateral ACAs formed during early embryogenesis.
