Differences in metabolic improvement after metabolic surgery are linked to the gut microbiota in non-obese diabetic rats

Figure 6 Analysis of gut microbiota in rats at 6 wk postoperatively. A: PcoA analysis of gut microbiota based on the OUT data of sleeve gastrectomy (SG), distal small intestine bypass (DSIB) and SHAM groups; B: Shannon index of biodiversity in the SG, DSIB and sham groups; C: Ratio of the relative abundance of SG, DSIB, and sham Firmicutes to Bacteroidetes; D: Relative abundance of gut microbiota composition at the genus level in the SG, DSIB and sham groups. DSIB: Distal small bowel bypass; SG: Sleeve gastrectomy.
