  • CKD-EPI, Chronic Kidney Disease Epidemiology Collaboration.

  • a HRs and 95% CIs.

  • b Multivariable model adjusted for: age, cause of end stage kidney disease, comorbid conditions recorded at time of dialysis initiation (coronary artery disease, peripheral vascular disease, heart failure, stroke, hypertension, diabetes, chronic lung disease, and malignancy), lifestyle factors (current smoker, drug and alcohol addiction), functional status indicators (inability to ambulate, inability to transfer independently), socioeconomic factors (employment status, insurance status at time of dialysis), baseline eGFR (from the CKD-EPI equation), albumin, and use of erythropoietin prior to dialysis initiation, incident year of cohort.

  • c Body weight measured prior to first dialysis treatment was included in extended model to account for differences in body size.

  • d Visit with a nephrologist or dietitian was substituted for pre-dialysis erythropoietin use in extended models to account for differences in care patterns prior to dialysis initiation.
