The relationship between the prevalence of each VALENCIA-assigned sub-CST and a woman’s self-identified race (a). Each bar represents the proportion of samples assigned to each CST in women whose race is Asian (n = 95), Black (n = 1,343), Hispanic (n = 110), White (n = 403), or Other (n = 17). For subjects who contributed multiple samples, the within subject relative prevalence of each CST was used in the calculation instead of their individual CST counts. We also examined relationships between the prevalence of each CST and a woman’s age (b). Only the prevalence of CST III was found to have a relationship with age among reproductive-age women. Bars represent the age distribution of subjects whose samples were (orange) or were not (grey) assigned to CST III. Older reproductive age women were less likely to have communities assigned to CST III than younger reproductive age women
