Associations of exposure to polycyclic aromatic hydrocarbons with hearing in U.S. Adults.
Article in Scientific reports, 2025. 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
Polycyclic aromatic hydrocarbons (PAHs) pollution and hearing loss are important issues in the environment and public health. However, current research still lacks data on their association in real-world environments. This study included 658 American adults who participated in the National Health and Nutrition Examination Survey (NHANES) from 2015 to 2016. The correlation between single PAH exposure and hearing was estimated by the weighted logistic regression, the overall association between mixed PAHs and hearing was evaluated by Bayesian kernel machine regression and grouped weighted quantile sum regression, and the important chemicals were identified in this study. The results showed that the 1-Hydroxynaphthalene (1-OHNa) was positively correlated with the hearing condition, hearing level and hearing threshold (OR = 1.41, 95% CI 1.08-1.84, P < 0.01; OR = 1.41, 95% CI 1.04-1.87, P < 0.05; OR = 4.34, 95% CI 1.74-10.81, P < 0.01, respectively). And 1-Hydroxypyrene (1-OHP) was positively correlated with the hearing condition and hearing threshold (OR = 1.83, 95% CI 0.99-3.36, P < 0.05; OR = 5.83, 95% CI 1.31-26.03, P < 0.05, respectively) after using covariate correction. The results of BKMR and WQS indicated a positive correlation between overall PAHs exposure and decreased hearing, and the higher the overall exposure to PAHs, the greater the risk of hearing loss. Further analysis revealed that 1-OHP was an important chemical substance related to PAHs and hearing. This result was consistent with the results of the single PAH exposure model. These insights provide a critical new perspective on the association between PAHs and hearing, highlighting the urgent need for strategies to reduce environmental pollution and protect human health.
