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
Endothelial senescence (ES) contributes to aging-related disorders and triggers a senescence-associated secretory-pattern (SASP), releasing Extracellular Vesicles (EVs), potentially impacting atherosclerosis. We used EVs from young (8 weeks) and aged (24 months) ApoE-knockout mice to detect ES in human aortic (HAEC) and coronary (CAEC) endothelial cells. Age-related atherosclerosis was confirmed by increased atheroma plaque formation in aged compared to young ApoE-knockout mice fed a high-fat diet, and the contribution of EVs from aged ApoE-knockout mice on ES was evidenced by a replicative senescence assay in cultured HAEC and CAEC, starting with the promotion of ES. A proteomic analysis depicted the recently PCSK9-associated CAP1 protein as a cargo component in EVs from aged animals and highly expressed in mouse and human endarterectomy plaques. Gene silencing of CAP1 inhibited HAEC and CAEC ES while overexpressing CAP1 in these cells restored the senescent-phenotype. The in vivo contribution of CAP1 was assessed by injecting CAP1-containing EVs isolated from aged ApoE-knockout mice into wild-type (WT) mice fed either a regular or high-fat diet. Compared to the EVs from young mice, the CAP1-containing EVs led to a pronounced ES along with the formation of intraluminal atheroma plaques. Similarly, young ApoE-knockout mice developed thickened and calcified atheroma plaques, along with increased ß-Gal-positive aortic staining when injected with EVs isolated from aged ApoE-knockout mice, like the atheroma plaques observed in aged ApoE-knockout animals. In conclusion, early molecular targets of ES may contribute to better management of atherosclerosis, in which here we unveiled CAP1 as a new molecular target.
