Diagnostic accuracy of serum ferritin.
(A) The ROC curve of serum ferritin with Hemoglobin ≥10g/dL. (B) Dot plot of serum ferritin in Hemoglobin <10g/dL and ≥10g/dL. The cutoff point for s-ft was found to be below 90 ng/mL (sensitivity: 69.1%, specificity: 72.1%, p < 0.001).
Fig 2.
Diagnostic accuracy of transferrin saturation.
(A) The ROC curve of transferrin saturation with Hemoglobin ≥10g/dL. (B) Dot plot of transferrin saturation in Hemoglobin <10g/dL and ≥10g/dL. The cutoff point for TSAT was found to be at least 20% (sensitivity: 77.6%, specificity: 48.8%, p = 0.302).

The relationship for serum ferritin and transferrin saturation with hepcidin.
(A) Serum ferritin showed a strong positive correlation with hepcidin [r = 0.78 (95% CI: 0.72–0.83, p < 0.001)]. (B) Transferrin saturation indicated a weak positive correlation with hepcidin [r = 0.18 (95% CI: 0.04–0.31, p = 0.010)].
