a
Level change reflects the the gradual modeled percentage change in mobility change immediately after an intervention compared with preintervention.
b
Slope change reflects gradual modeled percentage change in mobility per day after an intervention until the next intervention, modeled only for interventions occurring at least 5 days apart. Negative estimates indicate reduced mobility; positive estimates, increased mobility.
