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
backgroundPulmonary arterial hypertension (PAH) is an incurable disease initiated by endothelial dysfunction, secondary to vascular inflammation and occlusive pulmonary arterial vascular remodeling, resulting in elevated pulmonary arterial pressure and right heart failure. Previous research has reported that dysfunction of type 2 bone morphogenetic protein receptor (BMPR2) signaling pathway in endothelium is inclined to prompt inflammation in PAH models, but the underlying mechanism of BMPR2 deficiency-mediated inflammation needs further investigation. This study was designed to investigate whether BMPR2 deficiency contributes to pulmonary arterial hypertension via the NLRP3 (NOD-like receptor family protein 3)/GSDME (gasdermin E)-mediated pyroptosis pathway. METHODS AND
resultsNLRP3 knockout or short hairpin RNA interference of GSDME was performed in PAH animal models to investigate its effect on PAH progression. In addition, the effects of BMPR2 deficiency and restoration of BMPR2 by BMP9 (bone morphogenetic protein 9) or FK506 on pyroptosis were explored both in animal and cell models. Knockout of NLRP3 or short hairpin RNA interference of GSDME in animal models can alleviate the development of pyroptosis, accompanied with improved endothelial integrity, vascular remodeling, and right ventricular systolic pressure. Blocking BMPR2 is sufficient to induce NLRP3 upregulation and release of inflammatory factor IL-1β (interleukin-1β) in pulmonary arterial endothelial cells. Moreover, BMPR2 deficiency can induce GSDME-mediated pyroptosis through NLRP3 activation in 2 animal models, whereas activation of BMPR2 signaling by FK506 or BMP9 can reverse these phenotypes.
conclusionsThese findings provide evidence that loss of BMPR2 signaling promotes endothelial cell pyroptosis by enhancing NLRP3/GSDME signaling in PAH. Our findings may provide new insights to explore the inflammatory mechanism of PAH treatment.
