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

purposeTo investigate the prevalence and risk factors of overweight and obesity among children and adolescents in Hangzhou, thereby informing the development of tailored preventive strategies.

methodsThis school-based cross-sectional study conducted population-level analysis on 353 783 individuals across four districts. Using stratified cluster random sampling, we surveyed 6148 students from 28 schools through self-administered structured questionnaires to collect data on influencing factors. Univariate and multivariable logistic regression were used to screen possible risk factors of overweight and obesity.

resultsThe overall overweight and obesity rates were 27.20%, showing a significant decline in obesity prevalence with age (χ

conclusionsIn conclusion, before or after puberty, gender, boarding at school, higher fruit consumption frequency, breakfast skipping, increased toothbrushing frequency and bullying victimisation were significantly associated with overweight and obesity in Chinese children and adolescents. It is recommended that schools, families, hospitals and society should jointly take measures to encourage adolescent students to cultivate good learning-related behaviours and healthy lifestyles to maintain and promote physical health.
