Myopia prevalence among primary school students across different districts in Guangzhou: insights from a large-scale school-based screening.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo investigate the prevalence of myopia among primary school students in Guangzhou and examine variations by district, grade level, gender, and parental engagement.
methodsA total of 173,627 students from Grades 1-6 across 151 schools underwent vision screening between January and June 2024 in three districts of Guangzhou-Yuexiu (central urban core), Panyu (southern urban-rural fringe), and Huadu (northern rapidly urbanizing area). Uncorrected visual acuity and non-cycloplegic autorefraction were measured. Myopia was defined as uncorrected visual acuity < 5.0 and spherical equivalent refraction ≤ - 0.50 D.
resultsThe overall prevalence of myopia was 36.97%. Significant regional differences were observed: 37.67% in Yuexiu, 32.56% in Panyu, and 38.92% in Huadu (p < 0.001). Female students consistently showed higher prevalence than males in all districts (p < 0.001). A clear trend of escalating myopia prevalence with advancing grade level, especially around the transition from lower to upper primary grades. Parental query rates were highest in Panyu (62.13%), followed by Yuexiu (53.34%) and Huadu (47.06%) (p < 0.05).
conclusionDistrict-level disparities in myopia prevalence were identified, underscoring the importance of region-specific considerations in future prevention strategies.
