Estimates are in number of steps taken per day.

LB indicates Lower Bound; MT, MapTrek; UB, Upper Bound.

^aThe MT indicates MapTrek variable is an indicator for intervention membership.

^bThe Intervention variable is an indicator for the intervention period for both intervention and control subjects.

^cThe Days variable is the number of days since the intervention period started (−7 to 62).

^dThe MT×Intervention variable shows the effect of MapTrek after the intervention began.

^eThe MT×Days variable gives the effect of MapTrek over time.

^fThe Days×Intervention variable gives the effect over time after the intervention started.

^gThe MT×Intervention×Days variable given the effect of MapTrek over time after the intervention started.
