Lifestyle interventions and 24-hour movement behaviors in preschool children: a systematic review and meta-analysis.
Synthesis in Frontiers in public health, 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: Unhealthy 24-h movement behaviors, including insufficient physical activity, excessive sedentary behavior, excessive screen time, and inadequate sleep, are common among preschool children. However, evidence for the effectiveness of lifestyle interventions across these behavioral domains remains limited and inconsistent. This study aimed to evaluate the effects of lifestyle interventions on 24-h movement behaviors in preschool children. Methods: PubMed, SPORTDiscus, Scopus, Web of Science Core Collection, and CENTRAL were searched from inception to December 31, 2025. Randomized controlled trials involving children aged 2-6 years that evaluated structured lifestyle interventions targeting movement behavior domains were included. Random-effects meta-analyses were performed to estimate pooled mean differences (MDs) and 95% confidence intervals (CIs). Risk of bias was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool, and certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Results: Forty-three trials from 16 countries were included, comprising 13,659 preschool children. Lifestyle interventions were associated with increases in moderate-to-vigorous physical activity (MD 5.77 min/day, 95% CI 2.27 to 9.28; I Conclusion: Lifestyle interventions were associated with modest improvements in several 24-h movement behaviors in preschool children. However, heterogeneity was substantial across outcomes, and the certainty of evidence was low. These findings should therefore be interpreted as favorable but uncertain directions of effect rather than precise estimates of intervention efficacy. Future trials should adopt more standardized measurement and reporting methods, include longer follow-up, and examine time reallocation within the 24-h movement composition.
