Note: * denotes: P < 0.05, ^∧ denotes: P remains significant after Holm’s Bonferroni adjustment
SE Standard Error, CI Confidence Interval
A = intervention allocation effect on mediators
B = association between mediators and change in self-reported MVPA
C = total effect model
C′ = direct effect of intervention allocation on change in self-reported MVPA
AB = indirect effect of intervention allocation on change in self-reported MVPA through the hypothesised mediator
