Hazard ratios of mortality based on time-dependent Hb levels in all the patients.
Hb, hemoglobin; HR, hazard ratio; CI, confidence interval
Multivariate analysis sequentially adjusted models for covariates as follows:
aModel 1: age, sex, dialysis vintage, diabetes, cardiovascular disease, albumin, and high-sensitivity C-reactive protein
bModel 2: Model 1 + erythropoiesis-stimulating agent (ESA) dose, ferritin, and adjusted transferrin saturation (TSAT). Hazard ratios given for a 10-unit increase in age and two-unit increase in dialysis vintage.
ESA dose was categorized as untreated (reference), 1 to <5000, 5000 to <10000, 10000 to <15000, and ≥15000 IU/week.
Ferritin was categorized as <100, 100 to <500, and ≥500 ng/mL. TSAT was categorized as <20, 20 to <50, and ≥50.
