The difference was shown between T2 and T3.
These parameters were compared using Kruskal-Wallis test and the other parameters were compared using ANOVA.
EHRI: ESA hyporesponsiveness index; BMI: body mass index; WBC: white blood cell; TSAT: transferrin saturation; CRP: C-reactive protein; T. cholesterol: total cholesterol; nPCR: normalized protein catabolic rate; iPTH: intact parathyroid hormone.
