1 Where anemia = hemoglobin < 120 g/L; depleted iron stores = serum ferritin <15 μg/L or ferritin 15-50 μg/L + CRP > 10 mg/L; elevated iron stores = ferritin > 200 μg/L + CRP ≤ 10 mg/L; iron deficiency anemia = depleted iron stores + anemic; iron deficient erythropoiesis = serum soluble transferrin receptor (sTfR) > 2.75 mg/L. EAR = estimated average requirement.
2Analyses on a subset with venous blood sampling for hemoglobin determination.
3Analyses on a subset with soluble serum transferrin receptor measurements.
4Analyses on adjusted intakes for women aged 19-50 y using the probability method and women aged > 50 y using the EAR cut-point method, with women aged 18 y excluded.
