A positive coefficient means more of the microbe was present during the habitual diet, while a negative coefficient means less of the microbe was present during the habitual diet. All associations were to the kingdom bacteria, for readability the kingdom label is not presented. ^a Veillonellaceae is placed in the order Clostridiales in GreenGenes 13.5. However, according to the NCBI classification, it belongs to order Negativicutes
