The prevalence of relative EPO deficiency and iron deficiency stratified by CKD stages in anemic patients. Of patients with informed consent, 227 (78%) patients met the anemia criteria again at the time of enrollment. Non-CKD and CKD stages were defined as follows: Non-CKD and CKD stages were defined as follows: non-CKD, eGFR ≥60 mL/min/1.73 m2 and UACR <30 mg/g, CKD stage 1–2, eGFR ≥60 mL/min/1.73 m2 and UACR ≥30 mg/g creatinine; stage 3, eGFR <60 and ≥30 mL/min/1.73 m2; stage 4–5, eGFR <30 mL/min/1.73 m2. Abbreviations: EPO, erythropoietin; CKD, chronic kidney disease.
