Association between polycyclic aromatic hydrocarbons exposure and current asthma: a population-based study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPolycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that can cause a variety of health problems. This study sought to determine whether there was a relationship between PAHs and current asthma in adults.
methodsThis cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016 and employed multifactor logistic regression, subgroup analyses, and smoothed curve fitting to examine the linear and nonlinear associations between PAHs and current asthma.
resultsA total of 8729 adult participants were included in the study. We found a linear positive association between current asthma and the six PAHs. In the fully adjusted model, log 3-Hydroxyfluorene, log 2-Hydroxyfluorene, and log 1-Hydroxypyrene remained significantly associated with current asthma. Subgroup analyses stratified by smoking status, gender, age, and body mass index (BMI) showed consistent associations between PAHs and current asthma, with some subgroups displaying stronger positive correlations. Specifically, positive correlations between log 1-Hydroxynaphthalene, log 3-Hydroxyfluorene, and log 2-Hydroxyfluorene with current asthma were independently significant in smokers. Among women, log 3-Hydroxyfluorene and log 2-Hydroxyfluorene were also significantly associated with current asthma. In participants with a BMI ≥ 30 kg/m
conclusionsWe found a positive association between PAHs and current asthma in adults, with a variable relationship between log 1-Hydroxypyrene and current asthma, suggesting that high levels of 1-Hydroxypyrene exposure may increase the risk of current asthma. More prospective studies are needed to confirm our findings.
