Table 3 Moderating effect of gender and the level of physical activity in primary school (expressed in achieved the physical activity guideline or not) on the longitudinal changes in physical activity during the transition from primary to secondary school

From: Changes in physical activity during the transition from primary to secondary school in Belgian children: what is the role of the school environment?

Moderating effect of gender T1 – boys T1 – girls T2 – boys T2 – girls time point × gender (boys/girls)
