Beta diversity index between normal subjects (Normal), IDA patients (Pre), and subjects who recovered from IDA following iron supplementation (Post).

Index	Normal–Pre	Normal–Post	Pre–Post
Jenson–Shannon	* (p = 0.037)	N.S. (p = 0.672)	N.S. (p = 1.000)
Bray–Curtis	* (p = 0.017)	N.S. (p = 0.282)	N.S. (p = 0.929)
Generalized UniFrac	* (p = 0.045)	N.S. (p = 0.430)	N.S. (p = 0.853)
UniFrac	N.S. (p = 0.062)	N.S. (p = 0.329)	N.S. (p = 0.594)

The beta set significance between groups was determined with PERMANOVA (Permutational Multivariate Analysis of Variance). * p < 0.05; N.S., non-significant.
