Bacterial diversity values are given as the mean ± standard deviation at a rarefaction depth of 10,000 sequences per sample. Alpha diversity was compared between groups by means of a non-parametric t-test using the compare_alpha_diversity.py script of QIIME. The p values are shown in the last column in the following order: Healthy vs Intermediate, Healthy vs Vaginosis, and Intermediate vs Vaginosis.
