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