Figure 3. Results of PCA analysis based on OTU abundance, inter-group alpha diversity box map and multivariate analysis of variance of PCoA. The results of PCoA analysis based on OTU abundance (A) and inter-group alpha diversity box map (B). Multivariate analysis of variance of PCoA matrix scores (C). Letters a, b, c, d, and e in graph represent 10 mg/kg PSE-treated, 80 mg/kg PSE-treated, normal control, diabetes model, and 140 mg/kg MET-treated groups, respectively. The dots in the figure represent each sample. Different colours represent different groups of samples.
