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

backgroundPulmonary arterial hypertension (PAH) is characterized by excessive remodeling of the distal arterioles and arteries, driven by endothelial cell (EC) apoptosis and uncontrolled mural cell proliferation. Increasing evidence suggests immune dysregulation in PAH, but one crucial part of the immune system, the pulmonary lymphatics, has been largely overlooked. Patients with idiopathic PAH (IPAH) often develop abnormal tertiary lymphoid structures adjacent to remodeled arteries, yet the role of lymphatics in PAH pathogenesis and vascular remodeling remains unclear.

methodsMice with lymphatic EC-specific fluorescent label (Prox1-CreERT2::Rosa26-LSL-tdT) or lymphatic EC-specific deletion of Vegfr3 (vascular endothelial growth factor receptor 3; Prox1-CreERT2::Vegfr3

resultsPulmonary lymphatic vessels proliferated, branched, and dilated in response to hypoxia. Vegfr3 inhibition using MAZ51 or lymphatic EC-specific Vegfr3 deletion reduced hypoxia-induced lymphangiogenesis and was associated with worsened PH, right ventricular hypertrophy, and impaired drainage. Comparative single-cell RNA sequencing analysis revealed upregulation of

conclusionsThese findings identify adaptive lymphangiogenesis as a protective response in experimental PH and reveal a previously unrecognized CD74-VEGFR3 signaling axis in lymphatic ECs. Targeting lymphatic dysfunction may represent a novel therapeutic strategy to improve outcomes in PAH.
