Figure 2.

Results of the alpha diversity index analysis between normal subjects (Normal), IDA patients (Pre), and subjects who recovered from IDA with iron supplementation (Post). Species richness was analyzed using (A) Ace, (B) Chao1, (C) Jacknife, and (D) OTU, and species diversity was analyzed using (E) NPShannon, (F) Shannon, (G) Simpson and (H) Phylogenetic diversity. The analysis findings are shown as a boxplot, with the top and bottom of the box rep-resenting the first and third quartiles and the horizontal band representing the medi-an. The three groups did not differ statistically significantly from one another in any of the results analyzed above.
