Description: Ethnicity-associated taxa match between the HMP and AGP. Bar plots depict the log10 transformed relative abundance for individuals possessing the respective taxon within each ethnicity, ubiquity appears above (AGP) or below (HMP) bars, and the 25th and 75th percentiles are shown with extending whiskers. Mann–Whitney U tests evaluate differences in abundance and ubiquity for all individuals between pairs of ethnicities.
