Random effects linear regression analyses were performed to assess the relationship between average activity counts per minute and sleep duration, with and without Charlson Comorbidity Index tertiles, length-of-stay tertiles, physical therapy, baseline physical limitation due to physical health, and demographic characteristics as covariates.
