  1. aData used of the four RCTs that were included:
  2. -Delmas et al. [31]: Only the data from the control group were reported in the manuscript and therefore only those data were used in the review
  3. -Evenson et al. [45]: In each analysis model, the treatment condition (intervention vs. control) was included as a covariate. Therefore, both intervention and control group data could be used
  4. -Atlantis et al. [58]: no significant effects or trends were seen for any of the dependent variables. Therefore, data of both intervention and control groups were used
  5. -Schmitz et al. [48]: The self-reported PA and SLH were measured in spring whereas demographic and psychosocial variables were measured the previous fall (baseline data). Since the 16 schools of this study were randomized to intervention or comparison (delayed intervention) conditions after all baseline measures were taken, both intervention and control group data could be used for the current review
