Worldwide Burden of Hearing Loss Across Childhood and Adolescence, 1990-2021, and Projection to 2050.
Article in World journal of otorhinolaryngology - head and neck surgery, 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
Objectives: This article aims to analyze the trends in hearing loss (HL) prevalence and years lived with disability (YLDs) in children and adolescents from 1990 to 2021, and the corresponding health inequalities, decomposing causes, and future trends. Methods: This cross-sectional, population-based study used data from the Global Burden of Disease Study 2021 (GBD 2021) across 204 countries and territories. Individuals with HL aged 0-19 years were included in this study. Statistical analysis was performed using R. Results: There were 46,776,140 cases of pediatric HL globally in 2021, a 37.5% increase since 1990. The global prevalence rate increased from 1500.79 to 1721.44 per 100,000 population. Among the 5 SDI (sociodemographic index) regions, the highest number of prevalence cases of HL was in the Middle SDI, the lowest was in the High SDI, and the largest increase was in the Low SDI. Regionally, East Asia had the largest increase in prevalence. Among 204 countries, India had the highest number of HL cases in 2021, Madagascar had the highest prevalence rate, while Finland had the lowest prevalence rate. Globally, significant absolute and relative SDI-related inequalities were observed in the distribution of HL burden in 204 countries. By 2050, the prevalence of pediatric HL will be challenging, especially in the age group of 15-19 years, with male individuals being the most affected. Conclusion: Pediatric HL is an increasing global health issue with socio-geographic disparities. Thus, a comprehensive strategy to promote children's hearing health deserves ongoing prioritization in light of the consistently demonstrated demand.
