  1. aBetween group difference at follow-up controlling for baseline values of the outcome
  2. bExponentiated coefficient representing the between group difference in the change from baseline to follow-up
  3. cPACE is the reference category for all models so negative values for the primary outcome and values < 1 for the secondary outcomes indicate that scheduling of physical activity was, on average, lower in the Adapted PACE group than PACE
  4. dProbability that the true difference is < the pre-specified ∆
