Hearing Impairment Among Nursing Students: A hearWHO-Based Screening Study.
Article in Cureus, 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
Background Hearing loss among young adults is increasingly recognized as a public-health concern, often linked to harmful listening practices. While conventional audiometry is the diagnostic standard, smartphone-based screening tools such as the WHO's hearWHO offer a low-cost, scalable option for early detection. This study estimated the prevalence of possible hearing impairment in a cohort of nursing students using the hearWHO app and examined related risk factors. Methods In this cross-sectional study, 592 nursing students (≥18 years) at Subbaiah Institute of Nursing, Shivamogga, underwent hearing screening with the hearWHO Digits-in-Noise test. Participants who recorded scores below 50 dB were retested after 15 minutes, and the mean of the two readings was used for final classification. A pretested questionnaire collected demographic data, headphone habits, and relevant medical history. Data were analyzed in IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York, United States); significance was set at p < 0.05. Results The sample had a mean age of 20.5 ± 1.5 years and comprised 84.8% females. On initial testing, 475 participants (80.2%) scored 50-75 dB, 102 (17.2%) scored below 50 dB, and 15 (2.5%) scored above 75 dB. After reassessment, the prevalence of hearing impairment (mean score <50 dB) was 87 students (14.6%) (p = 0.000). Significant associations with poorer hearWHO scores were observed for age distribution (p = 0.018), type of headphones used (p = 0.045), and noncompliance with device volume alerts (p = 0.001). The average daily headphone use (2 ± 1.5 hours) showed no significant correlation with hearing thresholds (r = -0.009, p = 0.869). Conclusions The hearWHO application is a practical screening method for identifying potential hearing impairment in a student population. Behavioral factors related to listening practices, especially headphone type and disregard of volume alerts, were more closely linked to impaired screening results than either demographic variables or daily listening duration.
