Combined effects of xylene and noise exposure at realistic low levels on hearing impairment: a cross-sectional study in China.
Article in Preventive medicine reports, 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
Objectives: To investigate the combined effect of low-level xylene and noise exposure on hearing impairment in Chinese manufacturing workers and to provide evidence for occupational hearing protection strategies in China. Methods: A cross-sectional survey was conducted among 899 workers (295 co-exposed, 604 noise-only) in Jiaxing City, China from 2023 to 2025. Workplace noise and xylene concentrations were monitored, and pure-tone audiometry was performed with age-gender correction. Binary logistic regression and stratified regression analysis were used to evaluate risk factors for high-frequency hearing loss (HFHL). Results: The HFHL prevalence was 5.76% in the combined exposure group and 2.48% in the noise-only group ( Conclusions: Combined xylene and noise exposure exerts a significant synergistic ototoxic effect even when both exposures are within Chinese national occupational exposure limits.
