Note. The summary measure for sport participation and meeting physical activity guidelines are odds ratios and duration in Cohen’s d. A Cohen’s d of 0.2 is interpreted as small, 0.5 represents medium and 0.8 a large effect size. I²_2 = heterogeneity at Level 2 (i.e., between effect sizes from the same study); I²_3 = heterogeneity at Level 3 (i.e., between studies). R²_2 = variance explained at Level 2 (i.e., between effect sizes from the same study); R²_3 = variance explained at Level 3 (i.e., between studies)
