Fig. 2. Relative abundance of the taxa related to irritable bowel syndrome (IBS). The boxplots represent the relative abundance of (A) Proteobacteria, (B) Bacteroides, (C) Enterobacteriaceae, and (D) Faecalibacterium in the pre- and post-treatment samples. The abundances in the probiotic and placebo groups are shown on the left and right plots of each panel, respectively. Asterisks (*) indicate significant differences between the pre- and post-treatment samples. The phylum Proteobacteria (A) and genus Bacteroides (B) which are known to be abundant in patients with IBS, significantly decreased in abundance in the probiotic group (P = 0.022 and P = 0.003, respectively).
