Association between fine particulate matter and eczema: A cross-sectional study of the All of Us Research Program and the Center for Air, Climate, and Energy Solutions.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundThe prevalence of eczema has increased with industrialization. Industrial practices generate ambient air pollution, including fine particulate matter of diameter ≤ 2.5μm (PM2.5). Studies investigating the relationship between PM2.5 and eczema in the US are scarce. The objective of this study was to determine the risk of eczema with PM2.5 exposure in a diverse national cohort of American adults.
methodsIn this cross-sectional study, eczema cases in the All of Us Research Program were linked via three-digit zip code to average annual PM2.5 concentrations from the Center for Air, Climate, and Energy Solutions. Eczema cases and controls were compared using Pearson's χ2 test for categorical variables and one-way analysis of variance for continuous variables. The relationship between PM2.5 and eczema was assessed via logistic regression adjusting for demographic factors, smoking, and atopic comorbidities.
resultsIndividuals with eczema (n = 12,695) lived in areas with significantly higher PM2.5 concentrations than did individuals without eczema (n = 274,127) (0.83 x 10 μg/m3 v. 0.81 x 10 μg/m3, P < .001). PM2.5 concentration was significantly associated with eczema in univariable analysis (odds ratio 1.97, 95% confidence interval 1.77-2.19, P < .001), and in multivariable analyses, both controlling for demographics and smoking status (odds ratio 2.21, 95% confidence interval 1.98-2.47, P < .001) and with the addition of atopic comorbidities (odds ratio 2.38, 95% confidence interval 2.12-2.67, P < .001).
conclusionsThe odds of eczema increased with greater PM2.5 concentration in this large, diverse, adult American cohort. Ambient air pollution is an environmental hazard that influences inflammatory skin disease, suggesting possible targeted interventions.
