a
Proportion of samples with a concentration of bacteria. P-values were obtained with Chi square for the association presence of each bacteria and reported penile-vaginal sex.
b
Mean log10 concentration (geq/ml), if species is present. P-value was obtained by t-test for the association between mean log10 concentration and reported penile-vaginal sex.
