Temporal Trends in Hearing Aid Utilization in Korean Adults: A KNHANES-Based Study (2010-2022).
Article in Journal of Korean medical science, 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 public health issue that affects communication and quality of life. Hearing aids (HAs) are an effective rehabilitation tool, yet adoption rates remain low. To improve accessibility, South Korea revised its HA financial support policy in 2015. This study evaluates changes in HA adoption rates over the past decade and examines the impact of these policy modifications.
methodsThis study analyzed data from 9,994 (2020-2022) and 10,019 (2010-2012) individuals aged ≥ 40 years from the Korea National Health and Nutrition Examination Survey. HL was categorized based on pure-tone average thresholds: mild (26-39 dB HL), unsupported disabling (≥ 40 dB HL but not meeting financial aid criteria), lowest-grade hearing disability (≥ 40 dB HL in the better ear and ≥ 80 dB HL in the worse ear), and supported disabling (≥ 60 dB HL, eligible for financial aid). HA adoption rates were compared between the survey periods.
resultsThe overall HA adoption rate among individuals with HL significantly increased from 2.12% (2010-2012) to 4.73% (2020-2022) (
conclusionHA adoption rates have nearly doubled over the past decade, with the greatest increases observed among financially supported individuals and those in their 70s. Expanding financial support eligibility may further enhance HA adoption, particularly among those with disabling but unsupported HL, ensuring broader access to hearing rehabilitation.
