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

backgroundInter-organ crosstalk, particularly between adipose tissue and vasculature, plays a key role in obesity-induced cardiovascular dysfunction. Our previous work showed that adipose-derived extracellular vesicles (adiposomes) from obese donors impair arteriolar vasodilation through endothelial dysfunction, but their impact on vascular smooth muscle cell (VSMC) function remains unclear.

methodsVisceral adipose tissues were collected from 25 obese and 12 lean subjects undergoing bariatric and elective surgeries, and from high-fat diet-induced obesity (DIO) mice (n = 40). Adiposomes were isolated by ultracentrifugation, and arteriolar myogenic tone was assessed using pressure myography. Intracellular Ca

resultsObese arterioles exhibited greater myogenic tone than lean controls, a response also observed in healthy vessels exposed to obese adiposomes. Native VSMCs from obese subjects showed amplified acetylcholine-induced Ca

conclusionsThese findings underscore a pathogenic form of vascular-adipose crosstalk in obesity, where adiposome-mediated signaling alters VSMC excitability and vascular tone. Targeting this inter-organ communication axis may offer new strategies to reverse obesity-related vascular complications.
