Prevalence and sex differences in moderate-to-severe hearing loss among older adults: a cross-sectional study.
Article in BMC geriatrics, 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
backgroundAge-related hearing loss (ARHL) is common among older adults, and moderate-to-severe hearing loss (HL) is associated with adverse health outcomes. This study aimed to determine the prevalence of moderate-to-severe HL, identify its association with age, and assess potential sex differences across age groups.
methodsThis cross-sectional study included 2465 older adults from the China National Health Survey (between April and November 2023). Associations between age and HL were assessed using modified Poisson regression with robust variance. Multiplicative interaction terms were included to evaluate effect modification by sex.
resultsOverall, 26.8%, 19.1%, and 66.8% of older participants had moderate-to-severe HL in speech-, low-, and high-frequency ranges, respectively. Compared with the lowest quartile of age, the adjusted prevalence ratios for the highest quartile were 3.61 (95% CI, 2.90–4.50) for speech-frequency HL, 4.98 (95% CI, 3.69–6.70) for low-frequency HL, and 1.58 (95% CI, 1.45–1.71) for high-frequency HL(all P for trend < 0.001). Stratified analyses showed positive associations between age and HL across all frequency ranges in both sexes. A significant age × sex interaction was observed, indicating sex-specific age-related patterns of HL. Relative to the youngest age group (Q1), women showed a greater increase in the prevalence of moderate-to-severe HL across higher age groups than men.
conclusionIncreasing age was associated with a higher prevalence of moderate-to-severe HL across speech-, low-, and high-frequency ranges, with stronger age-related effects observed in women. These findings underscore the importance of early hearing assessment in older adults, and future research should investigate longitudinal changes, particularly the potential role of estrogen fluctuations around menopause in women.
