Table 3.
Multivariate survival analysis of the association between gait speed and instrumental activity of daily living (IADL), both measured within one year of HF, and all-cause mortality, restricted to individuals without impairment in either gait speed or IADL at baseline.

IADL impairment is defined as dependence (i.e., impairment) with ≥1 areas of IADL.
Gait speed impairment is defined as a walking speed of <0.8 m/s.
Adjusted for age at incident HF, gender (female vs. male), race (non-white vs. white), marital status (married vs. not), education (any college or higher vs. high school graduate or less), and income (>$25,000 vs. not), depression score, Mini Mental State Examination Score, hypertension, coronary artery disease, and chronic kidney disease, as determined at study entry.
