Prevalence of myopia among 26,697 school-aged children and adolescents in Taiyuan.
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
purposeInvestigation and analysis of the current status and influencing factors of vision screening-detected myopia among school-aged children and adolescents in primary, junior high, and senior high schools across various urban districts of Taiyuan, the capital city of Shanxi Province, to provide directions and recommendations for myopia prevention and control in the region.
methodsA cross-sectional survey study was conducted in March 2025, involving a total of 26,697 primary, junior high, and senior high school students in Taiyuan. Data were collected through questionnaires and non-cycloplegic autorefraction.
resultsThe overall screening prevalence of myopia among school-aged children and adolescents in Taiyuan City was 81.8%. The prevalence of myopia was significantly lower in males than in females (χ² = 45.57, P < 0.001).The screening myopia prevalence rates were 71.0% in primary school, 90.4% in junior high school, and 94.4% in senior high school, while the high myopia prevalence rates were 1.7%, 9.6%, and 17.2%, respectively. In primary and junior high schools, the detection rate of myopia was significantly higher in females than in males (χ² = 15.32 and 17.41; P < 0.001). However, in senior high school, the detection rate of myopia was similar between females and males (χ² = 3.57; P > 0.05).At the primary, junior high, and senior high school levels, female students exhibited a significantly higher degree of SER than male students (P < 0.05).The higher prevalence of both myopia and high myopia was significantly associated with the following factors: prolonged near-work duration (≥ 12 h per day, OR = 1.43), insufficient near-work distance, and parental myopia (at least one parent with myopia, OR = 4.02).
conclusionsIn 2025, the screening-detected prevalence of myopia and high myopia among school-aged children and adolescents in Taiyuan City, Shanxi Province, was notably high. This phenomenon was associated with factors such as near work activities and parental myopia. Furthermore, the detection rate of myopia exhibited an increasing trend with advancing educational stages, and the overall prevalence of myopia was higher in females than in males.
