n: Number of observed subjects in each group; TIBC: Total iron binding capacity;
SCT: Saturation coefficient of transferring; S: Difference statistically significant for
p < 0.05; NS: Difference not statistically significant for p > 0.05; the proportions of
various biochemical parameters were defined according to established references
[21,23,24,53]. |
