Trends in myopia prevalence among children and adolescents: a large-scale cross-sectional study in Shihezi, China.
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 7 papers, 1 of them a synthesis that pooled it.
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
purposeThe aim of this study was to understand the trends of myopia prevalence among children and adolescents in Shihezi, China.
methodsThis was a cross-sectional study using data from 2018 to 2023 from the Vision Surveillance Research Program for Students in Shihezi City. Describe the prevalence of myopia with 95% CIs in 31,265 children and adolescents in urban and rural areas, by sex and age. The prevalence rate and chain growth rate of myopia and spherical equivalent refraction in different ages were described the development of myopia.
resultsA total of 31,265 children and adolescents with a mean age of 11,91 ± 3.67 years were included in the study. The overall prevalence of myopia was 50.93%(15924/31265, 95% CI: 50.38 - 51.49%). The prevalence of myopia was 55.18% (8348/15128, 95% CI: 54.39 - 55.98%) for girls and 46.95% (7576/16137, 95% CI: 46.18 - 47.72%) for boys. Prevalence of overall, mild, moderate, and high myopia is higher in urban than in rural areas. The prevalence of myopia increases with age, with the highest chain growth rate of myopia of 69.18% at the age of 6 years, slowing down at the age of 12 years. Spherical equivalent refraction changes from positive to negative at 6-7 years of age.
conclusionsThe prevalence of myopia is higher in Shihezi, and myopia develops at an earlier age and the farsighted disappears earlier. The development of myopia begins to increase sharply at the age of 6 years and slows down by the age of 12 years, and the spherical equivalent refraction changes from positive to negative at the age of 6 to 7 years. For policy makers, it is even more important to prevent and control myopia at a younger age.
