Hazard ratios of mortality based on time-dependent Hb levels in all the patients.

Hb, hemoglobin; HR, hazard ratio; CI, confidence intervalMultivariate analysis sequentially adjusted models for covariates as follows:aModel 1: age, sex, dialysis vintage, diabetes, cardiovascular disease, albumin, and high-sensitivity C-reactive proteinbModel 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 Ferritin was categorized as Hazard ratios of mortality based on time-dependent Hb levels in all the patients.
