Statistical Analysis
death
REGRESSION, EVENT
We used an intention-to-treat analysis; all participants were observed until death, outcome event, or end of the 6-month follow-up. We examined baseline demographic characteristics using data provided by programs. We examined differences in our primary study outcome, time to nursing home admission, between the 2 interventions using a Cox proportional hazards regression model that adjusted for baseline covariates (ie, age, race and ethnicity, sex, living arrangement, and indicator for the program) to address possible imbalances across arms.
