Optimal dosage of exercise interventions for enhancing inhibitory control in overweight and obese children and adolescents: insights from a multilevel meta-analysis.

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: Overweight and obesity in children and adolescents are frequently associated with impairments in inhibitory control. Exercise interventions have been proposed as an effective means to enhance inhibitory control in this population. This study employs a three-level meta-analysis to assess the effects of exercise interventions on inhibitory control in overweight and obese children and adolescents, and further explores the dose-response relationship to identify the optimal intervention dosage. Methods: Systematic searches were conducted in the PubMed, Web of Science, Embase, Cochrane Library, and CNKI databases to identify relevant studies. Hedges' g was used as the measure of effect size, and a three-level random-effects model was implemented using the metafor package in R to address the dependency of multiple effect sizes within individual studies. Results: A total of 11 studies from four countries, involving 787 overweight and obese children and adolescents (average age: 8.75-14.06 years), were included. The meta-analysis revealed that exercise interventions significantly improved inhibitory control in this population, with consistent findings across both the three-level model ( Conclusion: Exercise interventions significantly enhance inhibitory control in overweight and obese children and adolescents. Based on current evidence, approximately 49 exercise sessions, each lasting about 48 min, may represent a potentially beneficial intervention dosage for improving inhibitory control. However, given the very low certainty of evidence, these findings should be interpreted cautiously and considered hypothesis-generating rather than definitive clinical recommendations.
