Average relative abundance of twelve key taxa across all of the samples used to define each of the thirteen sub-CSTs. Error bars represent the standard error of the mean as defined using 100 bootstraps of ten percent of the training dataset. These “average” communities define the reference centroids used by VALENCIA to assign new samples to sub-CSTs. Sub-CST IV-C0 is not dominated by any one species. CST V has 20% relative abundance of L. iners in addition to L. jensenii, indicating these two species can co-occur. This relationship is maintained over extended periods of time in some longitudinal profiles
