  1. Along the left are the bacterial taxonomic groups detected in the dataset. Across the top are the results from WATERS compared to the previously published results. Columns 1 and 3 provide the total abundance of all OTUs in that taxonomic category. Columns 2 and 4 provide the number of discreet OTUs observed in that taxonomic group. OTU abundance data for the Eckburg et al. dataset can be found on page 23 of the original publication's supplemental material [48].
