Continuous variables were presented as median (interquartile range); ESRD: end-stage renal disease; eGFR: estimated glomerular filtration rate; TIBC: total iron-binding capacity; TS: transferrin saturation; sTfR: soluble transferrin receptor; CRP: C-reactive protein; RBC: red blood cell count; WBC: white blood cell count; MCV: mean corpuscular volume; RDW: red cell distribution width.
