Mean ± SD. BL, baseline; N/A, non-applicable (for instance, when pairwise comparisons are not conducted due to the absence of interaction or when baseline MVPA values have been used to calculated tertiles); ns, non-significant; PA, physical activity; “+1-year”: end of the intervention; “+2-year”: 1 year after the end of intervention
1All the analyses output a significant time effect. A significant group effect was noted for the “vs. PA level at BL” analysis only
