Table 2. Relative abundance of the four major phyla in the fifteen countries. F/B ratio is calculated by dividing the relative abundance of the phylum Firmicutes by that of the phylum Bacteroidetes. P/A ratio is calculated by dividing the relative abundance of the phylum Proteobacteria by that of the phylum Actinobacteria.
