School and family based myopia education associations with myopia prevalence in Hefei high school students in the post-COVID-19 period.
Article in Scientific reports, 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
To investigate associations between multiple factors-including gender, parental myopia, outdoor activities, near work, and school/family-based myopia education-and myopia prevalence among high school students in Hefei in the post-COVID-19 period. A cross-sectional survey was conducted among 6475 senior high school students (aged 17-19 years) from 15 schools in Hefei, China, between March and May 2023. Visual acuity was measured using a standard logarithmic eye chart, and refraction was assessed via non-cycloplegic autorefraction with tropicamide-induced mydriasis. Myopia was defined as spherical equivalent (SE) < - 0.5 D. Self-reported questionnaires captured data on parental myopia, outdoor time, near work, sleep, and myopia prevention strategies. Data were analyzed using chi-square tests, tQUER-tests, and multivariate logistic regression, with sensitivity analyses accounting for potential overestimation due to non-cycloplegic refraction. Of 6414 participants (after exclusions), myopia prevalence was 85.3% (adjusted to approximately 82.5% in sensitivity analysis assuming 0.5 D overestimation). Females showed higher prevalence than males (88.9% vs. 82.9%; χ
