Outcome
- Type
- OTHER_PRE_SPECIFIED
- Title
- Number of Participants With All-cause Observation Stays
- Description
As-treated analyses using logistic regression models that included stabilized propensity score inverse probability of treatment weighting (IPTW) to balance baseline characteristics (socio-demographics, health behaviors, disease severity, comorbidities, inhalers/medications, and health care utilization in the prior year) between patients who participated in Walk On! intervention and the SC group. The first 2 months after randomization were excluded because it was expected that it would take approximately 2 months form the date of randomization to start the intervention.
- Time frame
- 2 to 12 months following randomization
