Histograms comparing the levels of serum iron-related markers in the PM group and IPA group. (A) Serum iron levels in the PM and IPA groups, p = 0.039. (B) Levels of unsaturated iron-binding capacity in the PM and IPA groups, p = 0.023. (C) Total iron-binding capacity in the PM and IPA groups, p < 0.001. (D) Percent transferrin saturation in the PM and IPA groups, p = 0.584. (E) Serum ferritin levels in the PM and IPA groups, p = 0.021.
