1 · What the graph read from it

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.

2 · The registry

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

Hereditary hemorrhagic telangiectasia (HHT) coexisting with moyamoya disease (MMD) is exceptionally rare. We report the first case of a 45-year-old female harboring two genetic variants implicated in vascular disease: a pathogenic mutation in ACVRL1 (c.1231C>T, p.Arg411Trp) and a novel variant of uncertain significance in RNF213 (c.13685C>T, p.Pro4562Leu). This case is remarkable for the concurrent manifestation of HHT-associated peripheral telangiectasia and MMD-characteristic intracranial arterial stenosis, suggesting a possible synergistic interaction between variants affecting distinct vascular signaling pathways. These findings offer new insights into the genetic mechanisms underlying complex hereditary vascular disorders and emphasize the importance of comprehensive genetic testing in diagnosing atypical vascular phenotypes.
