Table 3

The association of sex, a one-year increase in age, with frailty on risk of all-cause mortality at 146 months using cox regression models of proportional hazard. Frailty is represented in model 1 as a 0.01 increase in FI score whereas model 2 includes a 1-point increase in frailty phenotype score
