  1. TIBC: total iron binding capacity.
  2. For TIBC: One-way ANOVA.
  3. For the other parameters: Kruskal–wallis H test.
  4. p < 0.05 means that the distribution of values in each group is not equal.
  5. The letter a means that the difference is significant when compared to the controls separately.
  6. The letter b means that the difference is significant when compared to the moderate group separately.
