ROC curves for TfR, ferritin, and TfR-F Index (TfR/log ferritin ratio) in the identification of iron-deficient patients. The ROC curves are shown separately for the whole patient population (n = 129) (A) and for the distinction between the ACD (n = 64) and COMBI (n = 17) patients (B). TfR-F Index -, TfR ▩, ferritin ▪.
