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

Growth differentiation factor 2 (GDF2), also known as bone morphogenetic protein-9 (BMP9), is a key member of the transforming growth factor-beta (TGF-β) superfamily, playing a pivotal role in pulmonary vascular regulation and remodeling. Dominant variants in GDF2 are known to cause hereditary hemorrhagic telangiectasia type 5 (HHT5), a condition characterized by telangiectases and arteriovenous malformations (AVMs). More recently, recessive variants in GDF2 have been reported to cause pulmonary arterial hypertension (PAH) with or without features of HHT5. In this study, we identified a founder variant in GDF2 that potentially causes semidominant PAH in a cohort of 13 patients ranging in age from pediatric to middle-aged adults. Careful clinical evaluation revealed a wide range of ages of onset and disease severity. However, lack of HHT manifestations was a consistent clinical feature. Our results lend further support to GDF2 as a bona fide disease gene in the context of non-syndromic PAH and demonstrate the power of founder variants to reveal the full spectrum of disease variability.
