Association of near work and dim light with myopia among 1400 school children in a district in North India.
Article in Indian journal of ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Purpose: The aim of this study was to determine the association of near work and dim light with myopia among school children in a district in North India. Methods: This study included a total of 1400 children of either sex studying in classes 5-10 in various schools of a district in North India, after taking consent from their guardians. Visual acuity was measured using Snellen's chart. Myopes were called to our institute where wet retinoscopy was done and spectacles were prescribed. Results: There was a highly statistically significant correlation between myopia and increase in reading hours (P=0.001). There was a statistically significant correlation between myopia and >6hours of using mobile phones /week, more hours spent on using mobile phones correlated with an increased prevalence of myopia (P< 0.01). There was a statistically significant correlation between myopia and increasing hours of playing video games (P<0.01). We found a highly statistically significant positive correlation between the prevalence of myopia and reading in dim light (P=0.0006). Conclusion: There was a positive association between myopia and hours of doing near work. The prevalence of myopia increased with increased hours of doing near work (reading, playing video games and using mobile phones). The study showed a correlation between reading in dim light and myopia. Prevention of myopia may be possible by avoiding these risk factors.
