1 · What the graph read from 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.

2 · The registry

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

purposeMyopia is a growing global health issue, particularly among Chinese children and adolescents. This study aimed to investigate the prevalence and risk factors of myopia among children and adolescents in Shaanxi Province, China.

methodsA cross-sectional study conducted in 2021 included 261,504 participants from Guanzhong, Southern Shaanxi, and Northern Shaanxi. Ophthalmological examinations were performed, and refractive error was assessed using non-cycloplegic refraction to determine the spherical equivalent (SE). Myopia was defined as SE ≤-0.5 D and categorized into low (SE >-3.0 D), moderate (SE >-6.0 D), and high myopia (SE ≤-6.0 D). Data on age, gender, education level, and ethnicity were collected using structured questionnaires administered through face-to-face interviews.

resultsThe overall prevalence of myopia was 67.4% (95% CI: 67.20%-67.50%), with high myopia at 4.63% (95% CI: 4.55%-4.71%). Myopia was more common in females and increased with educational level, reaching 92.48% in senior high school students. Northern Shaanxi exhibited the highest prevalence of both myopia and high myopia. Regression analysis identified gender, education level, and region as significant risk factors.

conclusionsMyopia is highly prevalent among children and adolescents in Shaanxi Province, with notable gender, educational, and regional disparities. The findings underscore the urgent need for region-specific and education-level-targeted myopia prevention strategies.
