Case-mix model is adjusted for age, gender, race/ethnicity, pre-existing comorbid states, tobacco smoking, dialysis vintage, and primary insurance, marital status, presence of diabetes, serum ferritin, iron saturation, and weekly erythropoiesis-stimulating agent dose. MICS-adjusted model includes all of the case-mix covariates as well as body mass index and eight laboratory surrogate variables for nutrition and inflammation.
