Long-term exposure to ambient air pollution and epigenetic age acceleration in children.
Article in American journal of epidemiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Long-term exposure to ambient air pollution has been associated with epigenetic age acceleration (EAA) in adults, but its impact on children remains less understood. We analyzed data from 457 children (mean age: 7.9 years) in the Project Viva cohort (2007-2010, eastern Massachusetts, USA). We calculated the following EAAs from leukocytes: Horvath's epigenetic age acceleration (HorvathEAA), intrinsic epigenetic age acceleration (IEAA), and skin and blood epigenetic age acceleration (Skin&BloodEAA). We applied generalized additive models to evaluate associations of prior-365-day average and lifetime average exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as the distance to major roadways, with EAA. Results indicated that each IQR increase (1.9 μg m-3) in the prior-365-day average of PM2.5 was associated with 0.26 years (95% CI, -0.49 to -0.03) lower HorvathEAA, although it did not survive multiple testing adjustment. Similar patterns but with wider CIs were observed for IEAA (-0.22; 95% CI, -0.44 to 0.01) and Skin&BloodEAA (-0.04; 95% CI, -0.19 to 0.11). No associations were observed of exposure to lifetime average PM2.5, prior-365-day or lifetime average NO2 or O3, or distance to major roadways with EAA. These findings suggest higher prior-365-day average PM2.5 exposure may relate to lower HorvathEAA in children.
