Cox proportional hazard models were used to explore the simultaneous effects of the baseline frailty characteristics in separate models for nondepressed and depressed men and women. Wald χ2 values are listed; (df = 2 for the overall effect of each frailty characteristic, df= 1 for each subgroup comparison); Hazard ratios (and 95% CI) are for multiple predictor models with the inclusion of other frailty characteristics as covariates.
