*
Separate models were fitted for each diagnosis group; thus hazard ratios (HRs) are for each designated group compared with remainder of the sample.
†
Adjusted for age, sex, race, income, living alone, insurance status, number of pre-existing comorbidities, number of instrumental activity of daily living deficiencies, outpatient ED visits, and hospitalization within the previous 6 months.
MSK = musculoskeletal.
