Decreased Endothelial Cell Retinoic Acid Signaling Accelerates Progression of Single Ventricle Pulmonary Vascular Malformations.
Article in JACC. Basic to translational science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Pulmonary vascular malformations (PVMs) are vascular complications that universally develop in patients with single ventricle congenital heart disease after Glenn surgery, yet the pathogenesis of single ventricle PVMs remains unknown. Using a surgical rat model of Glenn circulation, single-cell RNA sequencing (scRNAseq) on whole lung samples identified dramatic endothelial cell (EC) gene expression changes post-surgery, including decreased all-trans retinoic acid (ATRA) signaling. Many gene expression differences (∼17% of all EC differentially expressed genes), including decreased ATRA signaling, were shared with 2 independent models of hereditary hemorrhagic telangiectasia arteriovenous malformations (AVMs). Subsequent dietary modification of vitamin A (Vit A) intake in rats, identified that dietary deficiency of Vit A increased PVM shunting severity, which was mitigated with excess dietary Vit A intake. Collectively, our study of post-Glenn PVMs identified shared patho-mechanisms with hereditary hemorrhagic telangiectasia AVMs, including decreased EC ATRA signaling, which is a novel potential target for treating AVMs.
