Gut Microbiota: A New Strategy to Study the Mechanism of Electroacupuncture and Moxibustion in Treating Ulcerative Colitis

Figure 4

The effects of electroacupuncture and moxibustion on β diversity of intestinal flora. (a) and (b) are PCoA analysis of intestinal flora; (c) is NMDS analysis of intestinal flora; (d) and (e) are PCA analysis of intestinal flora. (f) is grouping comparison of intestinal flora using partial least squares discriminant analysis (PLSDA). The distance between the different colored samples represents the similarity of microbiota composition in different groups, and a closer distance indicates higher similarity. All analysis was conducted on OTU level and the number of samples is 10 in each group.
