Analysis of the Association Between Weight Status and Myopia in Children and Adolescents and Development of a Screening Model Based on Body Fat Percentage.

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
purposeThis study examined the association between weight status and myopia in children and adolescents and compared the screening performance of body mass index (BMI) and body fat percentage.
methodsThis cross-sectional study included 8748 students aged 7-15 years. Height, weight and body fat percentage were measured, and myopia was assessed using non-cycloplegic autorefraction. The sample was randomly divided into training and validation sets. Logistic regression adjusted for sex, age, residence, physical activity and outdoor light exposure was used to examine the association between weight status and myopia. Mediation analysis treated physical activity as a categorical variable, with bootstrap resampling used to test indirect effects through BMI and body fat percentage. Receiver operating characteristic curves compared the screening performance of both indicators.
resultsOverweight or obesity was associated with myopia after full adjustment (odds ratio = 1.45, 95% confidence interval: 1.30-1.63). Categorical mediation analysis showed a direct protective association of higher physical activity with myopia, with no significant indirect effect through BMI or body fat percentage. In both training and validation sets, the area under the curve was 0.76 for BMI and 0.76 for body fat percentage. A body fat percentage threshold of 0.69 classified a high-risk group with higher myopia prevalence than the low-risk group (88.7% versus 52.1%).
conclusionOverweight or obesity is independently associated with myopia. BMI and body fat percentage provide comparable, low-cost tools for initial school-based risk stratification, while physical activity may protect against myopia independently of body composition.
