Abbreviations: EPO Erythropoietin, Post- Post-intervention, TSAT Transferrin saturation, iPTH Intact parathyroid hormone, CI Bias-corrected and accelerated confidence interval.

All analyses were adjusted for age, gender, hemodialysis duration, and baseline values of Kt/V and outcome variables.

ΨBoth baseline and post-intervention TSAT were included in regression analysis in logarithmic scale.

*P value < 0.05 or 95%CI (with bootstrap method) not including null value was considered as statistically significant.
