Abdominal obesity among Chinese children and adolescents: a systematic review and meta-analysis of prevalence and study-level heterogeneity.
Synthesis in Frontiers in nutrition, 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
Background: Abdominal obesity in youth is a nutrition-related public health concern and may capture cardiometabolic risk beyond BMI. We aimed to estimate the pooled prevalence of abdominal obesity among Chinese children and adolescents and explore study-level heterogeneity. Methods: PubMed, Web of Science, Embase, CNKI, WanFang, and VIP were searched from inception to December 31, 2025. Eligible studies reported abdominal obesity prevalence among children and adolescents in China. Random-effects meta-analysis of proportions was performed. Subgroup analyses and exploratory meta-regression assessed variation by survey year, sex, urban-rural setting, diagnostic criterion, and study quality. Results: Twenty-eight studies contributing 30 prevalence estimates were included. The pooled prevalence was 20.0% (95% CI: 19.0-22.0%; 95% prediction interval: 11.9-31.3%), with very high heterogeneity (I Conclusion: Standardized waist-based surveillance, alongside BMI, is needed to improve comparability across studies and to support school- and community-based prevention strategies targeting central adiposity in Chinese youth.
