Classroom Environmental Determinants of Poor Vision in Chinese Schoolchildren - Guangdong Province, China, 2024.
Article in China CDC weekly, 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
What is already known about this topic?: The prevalence of poor vision among Chinese children and adolescents has been progressively increasing, constituting a significant public health concern. As the primary visual setting for students, the classroom environment may have a profound impact on ocular health. What is added by this report?: This study revealed a poor vision detection rate of 60.22% among primary and junior high school students. The statistically significant relevant factors were blackboard reflectance, desk-chair allocation compliance rate, and desktop illuminance uniformity. What are the implications for public health practice?: This study provides scientific evidence and prioritizes recommendations for modifying classroom environments. It supports targeted environmental interventions as a priority in school-based myopia prevention strategies.
