Prevalence and determinants of hearing loss among the aging population in China: insights from the 2023 China National Health Survey.
Article in European journal of medical research, 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
backgroundHearing loss (HL) is a prevalent issue among the aging population in China, with significant health and social consequences. Understanding the epidemiological situation and contributing factors to HL in post-pandemic China is critical for developing effective prevention and intervention strategies.
methodsInformation on participants' education level, income, noise exposure, tinnitus history, smoking and drinking habits, COVID-19 infection history, and vaccination status was collected through interviews. Additionally, height and weight were measured on-site and fasting blood samples were drawn for blood glucose and serum lipid level testing.
resultsThe overall prevalence of HL was 74.82%, while the prevalence of high-frequency HL (HF-HL) was 89.10%. Notably, 21.47% of subjects had HF-HL without standard-frequency HL. Multivariable logistic regression identified age, sex, location, education level, noise exposure, tinnitus, ear disease history, smoking, hypertension, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection history, and lipid levels as potential influencing factors for HL. The relationship between lipid metabolism disorders and hearing is complex; triglycerides (TG) exhibited a protective effect on hearing under certain conditions (e.g., when total cholesterol (TC) was < 5.2 mmol/L and TG ≥ 2.3 mmol/L for standard PTA; TC < 5.2 mmol/L and all TG levels for high-frequency PTA).
conclusionThe incidence of hearing loss among older individuals has increased in post-pandemic China. Early identification of at-risk populations, expanded community hearing screening, and public education on hearing health could help more aging individuals prevent hearing decline.
