Data are hazard ratio (95% confidence interval) adjusted for covariates in Model 4, Table 2.

^*Excludes women who had functional limitations in activities of daily living (ADL) and reported no recreational physical activity (PA).

ADL, activities of daily living.

HF, heart failure.

MET-hr/wk, metabolic equivalent hours per week.
