Figure 2: Numbers of taxa per subject using three different taxon definitions. Taxon definitions of 99%, 98%, and 97% OTUs were assigned using the Mothur package. The shaded boxes encompass the 25th to 75th percentiles of the data, the boldface lines indicate means, and the whiskers span the 5th to 95th percentiles. The asterisks indicate significantly (P<0.001) differences in mean values for subjects with BV versus subjects without BV, as determined by t tests.
