Only those genera for which q < 0.1 or log₁₀(LDA score) > 1.8 are presented. Genus has been sorted by log₁₀(LDA score) in descending order within each phylum

RA relative abundance, HDP healthy dietary pattern, WDP western dietary pattern, B Bacteroidota, F Firmicutes, P Proteobacteria

^*The difference in means is also presented, because in some cases both medians are 0.00
