Phylum-level and genus-level analyses of the 27 samples. a Overall fecal microbiota composition of the samples at the phylum level in groups A and B. b Comparison of the relative abundances of the three main bacterial phyla in groups A and B. c Overall fecal microbiota composition of the samples at the genus level in groups A and B. d Comparison of the relative abundances of the four main bacterial genus in groups A and B. The relative abundances of Romboutsia, Lactobacillus, Bacteroides, and Enterococcus are shown on the y-axis. Boxes with one asterisk indicate significant differences between the two groups at p < 0.05 using a t test
