Hazard Ratios for Death for groups stratified by Coronary Disease, smoking status and age. P value for each group versus referent (no disease, non-smoker), **P < 0.001. Model adjusted for demographic characteristics (sex and race), clinical conditions (diabetes, hypertension, peripheral vascular disease, cerebrovascular disease, heart failure, pulmonary disease, cancer, AIDS, body mass index), lifestyle and functional factors (difficulty in walking and transfers, alcohol use, and employment status), erythropoietin use pre-dialysis, and laboratory factors (serum albumin, eGFR at dialysis initiation). Age was modeled in quintiles
