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
Characterizing the relationship between DNA methylation and circulating proteins is critical to understanding the epigenetic regulation of the human plasma proteome. Here, we performed an epigenome-wide association study of 5,032 circulating proteins in 1,449 White and 315 Black participants from the Atherosclerosis Risk in Communities cohort. We identified 12,500 significant protein quantitative trait methylation (pQTM)-protein associations involving 1,647 proteins. Among 7,796 unique pQTMs, 14.7% were classified as cis-pQTMs, which were enriched for fundamental cellular processes, whereas trans-pQTMs were predominantly linked to immune-related functions. Trans-pQTMs also exhibited stronger associations with demographic, lifestyle, and clinical traits as compared with cis-pQTMs. We identified proteins such as GM2A and EPHB6, whose expression appears to be strongly associated with DNA methylation, suggesting potential as targets for epigenetic-based therapeutic interventions. These findings demonstrate the extensive impact of DNA methylation on the circulating proteome through cis- and trans-regulatory mechanisms and underscore the influence of population-level traits on epigenetic regulation. These findings highlight a broad impact of DNA methylation on circulating proteins through both cis- and trans-regulatory mechanisms and the roles of population-level phenotypes.
