Richness and diversity values for taxon definitions of sequence similarity cutoffs of 99%, 97%, and 95% and best matches to taxon designations in NCBI for all 16S rRNA gene sequences generated from subjects with (BV+) and without (BV−) BV. Richness values in parentheses represent average Chao1 richness estimates calculated as described in the text.
