Likelihood of any MVPA
Across all groups in the logit model, likelihood of engagement in any (versus no) daily MVPA increased from baseline (range: 0.72 to 0.81) to intervention (range: 0.84 to 0.89). There was a significant Neighborhood Walkability x Reinforcement Timing x Phase interaction (OR = 0.91, 95% CI: 0.85, 0.97, p = .002). As shown in the left column of Fig.
