Prevalence and risk factors of myopia among school-aged children and adolescents in Xi'an, China.
Article in International journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimTo evaluate the prevalence of myopia and identify its associated risk factors among children and adolescents in Xi'an, China.
methodsIn a school-based cross-sectional design, students ranging from kindergarten to high school across Xi'an were enrolled. Ophthalmic examinations were performed to assess refractive status
resultsThe study included 156 416 participants, with 81 389 boys (52.0%) and 75 027 girls (48.0%). The prevalence rates of myopia were 65.67% for boys and 68.83% for girls. Data collection occurred over two consecutive years, 2021 and 2022, with 78 849 and 77 567 participants, respectively. The prevalence of myopia was 67.65% in 2021 and decreased slightly to 66.71% in 2022. The high myopia rates were 3.85% and 3.43% for these years, respectively. Analysis revealed significant risk factors including gender, age, and educational level, with a distinct positive correlation between increased educational level and higher myopia prevalence. Notably, both genders exhibited a significant decrease in moderate myopia over the study period, with reductions of 1.7% and 1.2%.
conclusionThis comprehensive study underscores the substantial prevalence of myopia among school-aged children and adolescents in Xi'an, marking it as a significant public health concern. The correlation with higher educational levels suggests the need for targeted interventions aimed at myopia prevention and management. These findings contribute critically to the body of knowledge necessary for formulating effective public health strategies in Xi'an and potentially other similar regions.
