Electroacupuncture May Inhibit Oxidative Stress of Premature Ovarian Failure Mice by Regulating Intestinal Microbiota

Figure 5

The distribution of bacteria between the three groups differed. (a–b) At the end of the species accumulation and dilution curves, the upward trend flattened which indicated that most OTUs have been captured and the sample size has been sufficiently large to cover the majority of information on microbial diversity. (c) The rank abundance analysis showed that the compositions of microorganisms within each group were similar in their richness and evenness. (d–f) Chao1 and Ace count for the species richness or the number of species presented and the Simpson index reflect species richness and community evenness (, , ). (g) Based on the PERMANOVA of differences between groups and differences within groups, it is clear that there is a significant difference between the three groups (, ). (h) Principal coordinate analysis (PCoA) of unweighted UniFrac distance matrices was used to analyze the intestinal microbiota in different groups. All data were normally or approximately normally distributed.
