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
Atherosclerosis is a cardiovascular disease caused by cholesterol-laden arterial plaques. This study evaluated the correlation between interleukin-6 (IL-6), its receptors (IL6R/CD126), and glycoprotein 130 (gp130) alongside atherosclerosis biomarkers in a cohort of 142 subjects, equally divided between lean and obese individuals. Subsequent analyses used THP-1-derived macrophages to assess the biochemical impact of inhibiting IL-6 receptors. IL-6 secretion increased with atherosclerosis in obese subjects, while IL6R/CD126 and gp130 on monocytes decreased. Pharmacological gp130 inhibition altered lipid metabolism, increasing LDLR gene expression and cholesterol synthesis via SREBF2 and mevalonate kinase, along with HMG-CoA reductase at protein levels. gp130-deficient cells produced more cholesterol and had lower ABCA1 levels, suggesting hindered cholesterol efflux. Filipin III staining confirmed cholesterol retention in gp130-inhibited cells. Ex-vivo investigation on lean PBMCs further defined the impact of gp130 inhibition on the reduction of cholesterol efflux. Our results indicates gp130 is crucial for macrophage reverse cholesterol transport and may be a target for atherosclerosis treatments.
