Correlation between perfluoroalkyl and polyfluoroalkyl substances and adult asthma in the NHANES.
Article in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Per- and polyfluoroalkyl substances (PFAS) are pervasive organic compounds that have garnered significant attention due to their potential impacts on human health, particularly in relation to asthma, though current evidence remains limited. This study aimed to examine the association between PFAS exposure and adult asthma using a sample of 7106 participants aged 20 years and older from the NHANES survey, spanning 2003 to 2018. Survey-weighted multivariable logistic regression models, subgroup analysis, weighted quantile sum and Bayesian kernel machine regression models were employed to probe the relationship between PFAS and asthma. In the multivariable logistic regression analysis, higher log10-transformed perfluorooctane sulfonic acid (PFOS) and PFNA concentrations were significantly associated with lower odds of asthma (PFOS: OR = 0.76, 95% CI: 0.61-0.96; PFNA: OR = 0.77, 95% CI: 0.60-0.99). The inverse link between PFAS co-exposure and asthma incidence persisted across multi-pollutant models, weighted quantile sum regression, and Bayesian kernel machine regression models, with PFOS emerging as the primary negative influencer. In conclusion, this study highlights PFAS exposure is inversely associated with asthma risk in adults.
