Unadjusted and adjusted HRs and 95% CIs for all-cause mortality associated with the pattern of vascular access type within the first year of hemodialysis (reference: CVC use only group). Unadjusted model included the pattern of vascular access use; case mix–adjusted model included the unadjusted model covariates, as well as age, sex, race/ethnicity, primary insurance type, comorbid conditions (diabetes mellitus, hypertension, atherosclerotic heart disease, congestive heart failure, other cardiovascular disease, cerebrovascular disease, dyslipidemia, chronic obstructive pulmonary disease, liver disease and history of malignancy) and dialysis dose as measured by single-pool Kt/V; case mix +  MICS model included the case mix–adjusted model covariates, as well as BMI and clinically relevant laboratory variables (WBC count, hemoglobin, serum albumin, creatinine, bicarbonate, uncorrected calcium, phosphorus, iPTH, total iron binding capacity and nPCR); case mix + albumin model included the case mix–adjusted model covariates, as well as serum albumin.
