Gut microbial diversity in response to iron supplementation.
PD
The change in four different alpha diversity metrics between weeks 0 and 12 were examined for each trial arm, as depicted in For each iron supplement trial arm, changes in richness, evenness, Faith’s phylogenetic diversity (PD), and Shannon diversity were measured between weeks 0 and 12 and compared to the placebo group using a Wilcoxon Rank Sum Test and a Holm-Bonferroni method with family-wise error rate Weighted UniFrac, Bray-Curtis dissimilarity, and unweighted UniFrac were used for beta diversity analysis to identify any structural changes in the gut microbiome of trial participants. There were no significant changes in the pairwise distances between weeks 0 and 12 for those who received ferrous bisglycinate (
