a Cladogram showing the differentially abundant taxa. This plot shows the different levels of taxonomy. Gray indicates bacteria higher in the habitual diet and red indicates those higher in the gluten-free diet. The different circles represent the different taxonomic levels. (From inside to outside: Kingdom, Phylum, Class, Order, Family, Genus, and Species). b Comparison of the abundance of Veillonellaceae* in the gluten-free diet vs. habitual diet. In the plot, the aggregate “overall weeks” including correction is shown. * Veillonellaceae is placed in the order Clostridiales in GreenGenes 13.5. However, according to the NCBI classification, it belongs to order Negativicutes
