Figure 3: Receiver operator curve (ROC) plots for sTfR_f, sTfR, TIBC, and per_SAT values for different ferritin cut-offs in Group 2 and 3 (cases). Log_ferritin- Logarithmic value of serum ferritin level, sTFR - serum transferrin levels, sTFRlog_f - ration of sTFR to log ferritin S Iron - Serum iron concentration, TIBC - Total iron binding capacity, per_SAT - Percentage saturation
