Estimated Prevalence of Compliance With Muscle-Strengthening Activity Recommendations in Children and Adolescents: A Meta-Analysis.
Synthesis in Acta paediatrica (Oslo, Norway : 1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
aimTo estimate the prevalence of meeting the World Health Organization (WHO) guidelines for muscle-strengthening activities in children and adolescents, specifically engaging in these activities at least 3 days per week, and explore, whenever possible, this prevalence according to sociodemographic and healthy habits factors.
methodsFour databases were systematically searched for studies published from inception to January 2025. Eligible studies included articles with samples of children and adolescents reporting the prevalence of meeting the muscle-strengthening activities guidelines.
resultsTwenty-nine studies comprising 1 273 544 children and adolescents (49.40% girls; mean age: 13.40 years) from 36 countries were included. Estimated prevalence of muscle-strengthening activities was 38.51% (95% CI, 34.35% to 42.75%), based primarily on studies involving adolescent populations, with limited data available for children aged 6 to 12 years. According to the subgroup analyses, the predictors that favour compliance with the muscle-strengthening activity guidelines are being a boy, having normal weight, meeting the aerobic physical activity recommendations and receiving high family support for engaging in physical activity.
conclusionOnly 4 out of 10 children and adolescents meet the WHO muscle-strengthening activity guidelines. Targeted efforts are needed, particularly for girls and those with lower support or physical activity levels, to improve participation and youth fitness.
