Patterns and Severity of Hearing Loss in Patients Undergoing Pure Tone Audiometry in Eastern Nepal: An Observational Study.
Observational study in JNMA; journal of the Nepal Medical Association, 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
Introduction: There is limited evidence describing the demographic patterns of hearing loss in the Nepali context. This study aimed to analyze the audiometrie profiles of patients undergoing pure tone audiometry in a tertiary care centre of Eastern Nepal. Methods: A retrospective analysis was conducted on all patients undergoing pure tone audiometry at B.P. Koirala Institute of Health Sciences, Nepal, between April 2023 and July 2024. Ethical approval was obtained from the Institutional Review Committee (IRC-163-081-82). Census sampling was used, and data on demographics and audiometric profiles were compiled in Microsoft Excel and analyzed with SPSS version 25. Results: Among 3,468 patients (mean age: 42 years, SD ± 20.27 years, M:F ratio 1:1.2), 2629 (75.8%) exhibited some degree of hearing loss. Mild hearing loss was observed in 1225 patients (35.32%). Sensorineural hearing loss was seen in 1010 (32.21%) male vs 1130 (29.77%) female ears and conductive hearing loss was seen in 476 (15.18%) male vs 620 (16.33%) female ears. Sensorineural hearing loss increased from 17 (6.59%) in children under 10 years to 165 (80.88%) in age 80 and above, while conductive hearing loss declined from 87 (33.72%) in those under 10 to 9 (4.41%) in above 80 years. Conclusions: In this cohort of participants, three-quarters exhibited some degree of hearing loss, with mild loss being more common. Sensorineural loss increased with age and predominant in males, while conductive loss was more frequent in younger patients and females.
