Comparisons of microbial community composition between the five health status groups.

Tests were performed with PERMANOVA using Bray-Curtis dissimilarity measures of OTU abundances (results from the 97% identity cutoff are shown here). The Pseudo-F statistic comparing all five groups is 3.56 with a permutation test P value of 0.001. The groups are defined as ANGH: Acute Necrotizing Gingivitis healthy site, ANG: Acute Necrotizing Gingivitis lesion site, C: Control, NH: Noma Healthy site, N: Noma lesion site. *P-values corrected for multiple comparisons using the False Discovery Rate.
