  1. Note: a: effect size in children under 5 years; b: effect size in children 5 to 11 years, h /wk hour per week, min/d minutes per day, SB sedentary behaviour, SMD standardized mean difference, 95% CI 95% confident interval
  2. Bold numbers indicate non-significant effect sizes. Negative numbers indicate reduction
  3. #Meta-analyses reported post-intervention change-from-baseline difference between intervention and control group)
  4. *Meta-analysis did not report effect size for adults and children separately
  5. %Standardized mean difference, where effects were measured in different scale
