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

backgroundThe rapid economic development in China has led to significant challenges in air pollution. This study examines the relationship between prolonged exposure to air pollution and the prevalence of overweight and central obesity among Chinese children and adolescents.

methodsA total of 161,093 children and adolescents (aged 9–18) from 32 provinces in China were analyzed. Ambient air pollution (PM2.5, PM10, SO2, NO2, O3, CO) was assessed using satellite models. Overweight and central obesity were measured via BMI, waist circumference, and Waist-to-Height Ratio (WHtR). Mixed-effects regression models were adjusted for demographic and behavioural factors, with sensitivity analyses conducted for exposure windows.

resultsPM2.5 was significantly associated with an increased risk of being overweight (OR = 1.212, 95% CI: 1.169–1.257, p < 0.001). SO2 (OR = 1.103, 95% CI: 1.069–1.139, p < 0.001), NO2 (OR = 1.069, 95% CI: 1.051–1.087, p < 0.001), and reciprocal CO (OR = 1.052, 95% CI: 1.043–1.061, p < 0.001) also showed positive associations. In contrast, PM10 (OR = 0.954, 95% CI: 0.938–0.969, p < 0.001), AQI (OR = 0.959, 95% CI: 0.935–0.983, p < 0.001), and O3 (OR = 0.949, 95% CI: 0.935–0.962, p < 0.001) were negatively associated with overweight. For central obesity, AQI (OR = 1.118, 95% CI: 1.095–1.141, p < 0.001) and NO2 (OR = 1.065, 95% CI: 1.051–1.079, p < 0.001) showed positive associations, while PM10 (OR = 0.901, 95% CI: 0.889–0.913, p < 0.001) and O3 (OR = 0.973, 95% CI: 0.962–0.985, p < 0.001) were inversely associated. SO2 and CO−1 were not statistically significant for central obesity after full adjustment. Boys, high school students, and children from low-income or southern regions exhibited stronger associations. Similar trends were observed for central obesity.

conclusionProlonged air pollution exposure significantly increases the risks of overweight and central obesity in Chinese children and adolescents.
