Spatial and temporal associations between physical establishment density and hearing difficulty across US counties.
Article in PloS one, 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
Hearing loss is a critical public health issue in the United States, affecting more than 15% of American adults. Existing studies have primarily focused on physiological and socioeconomic factors associated with hearing health. This study investigates the spatial and temporal associations between physical establishment density and hearing difficulty rates across US counties. Bivariate correlation analysis shows that counties with denser physical establishments generally exhibit lower hearing difficulty rates, and vice versa. Counties with lower hearing difficulty rates also tend to exhibit denser road networks, higher socioeconomic status, younger population structures, better insurance coverage, and higher educational attainment levels. After controlling for road density and other sociodemographic covariates in regression analyses, physical establishment density becomes positively associated with hearing difficulty rate. Our analyses indicate that road density largely drives this sign reversal and reflects broader infrastructure accessibility and urban service connectivity. We also identified hearing-health-risky physical establishments, representing environments potentially associated with elevated occupational or lifestyle-related noise exposure. Hearing-health-risky physical establishment density showed a stronger positive association with hearing difficulty rates than overall physical establishment density. Temporal clustering analysis further reveals that counties exhibiting increasing trends in hearing difficulty rates during 2012-2021 tended to have higher physical establishment density. Our findings suggest that counties characterized by denser built environments and better socioeconomic conditions currently exhibit lower hearing difficulty rates at the aggregate level, while urbanized environments may also be associated with growing long-term hearing-health risks. These findings provide implications for hearing-related urban planning, environmental noise management, and public health policy.
