Data are shown as mean ± standard deviation or n (%). Difference was analyzed using Student’s t-test for continuous variables and Pearson’s chi-square test or Fisher’s exact test for categorical variables.
MCO, medium cut-off; SBP, systolic blood pressure; DBP, diastolic blood pressure; ESA, erythropoiesis stimulating agent; ERI, erythropoietin resistance index.
