Tinnitus prevalence and characteristics in the United States: insights from a cross-sectional analysis of the 2019-2022 Apple Hearing Study cohort.
Article in BMC public health, 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
backgroundTinnitus is a complex condition with significant heterogeneity in its presentation, and its risk factors remain poorly characterized, posing challenges for prevention, diagnosis, and treatment. This study aimed to assess the prevalence, characteristics, and risk factors of tinnitus in the United States (U.S.) using large-scale survey data.
methodsWe conducted a cross-sectional analysis of 125,252 volunteer adults (≥ 18 years) enrolled in the Apple Hearing Study, a nationwide app-based cohort of iPhone users in the U.S. (November 2019–November 2022). The outcomes were the weighted prevalence of any tinnitus and bothersome tinnitus, measured using self-reported tinnitus frequency, duration, awareness, loudness, and interference with hearing. Age-adjusted and multivariable logistic regression models were applied to analyze the odds ratios of self-reported potential risk factors on tinnitus, and a weighted decision tree identified the strongest predictors of bothersome tinnitus.
resultsThe estimated weighted national prevalence of any tinnitus was 30.8% (95% Confidence Interval [CI]: [30.3%, 31.2%]) and bothersome tinnitus was 11.6% (95% CI: [11.3%, 11.9%]). Controlling for age, sex, race/ethnicity, and other sociodemographic characteristics, self-rated hearing ability was the strongest risk factor for any tinnitus (odds ratios of 4.52 [95% CI: 4.03–5.06] and bothersome tinnitus 8.88 [95% CI: 7.52–10.49], comparing poor to excellent hearing). The odds of both types of tinnitus increased with age, peaking in the 60–64 age group (2.01 [95% CI: 1.77–2.28] for any tinnitus and 2.72 [95% CI: 2.24–3.92] for bothersome tinnitus) after adjusting for the same set of variables. Non-Hispanic Whites had higher odds of any and bothersome tinnitus compared to other race/ethnicities. A reported history of occupational noise exposure was associated with higher odds of any and bothersome tinnitus.
conclusionsApproximately 3 in 10 U.S. adults are estimated to experience any tinnitus, and about 1 in 10 affected by bothersome tinnitus. Tinnitus is associated with worse self-rated hearing ability, age, race/ethnicity, and a history of workplace noise. These results align with prior epidemiological estimates and demonstrate the feasibility of using app-based platforms to collect large-scale, high-quality hearing health data.
