The LEfSe with default parameters was used to identify species with significant differences between groups. The detailed statistical method used in LEfSe software (version 1.0) was the Kruskal-Wallis test. Increased items are indicated by ↑ and decreased items by ↓. All of the trends indicated in the table had statistical significance (LDA score >4). CO, control group; SG, sleeve gastrectomy; RYGB, Roux-en-Y gastric bypass; SG0/3, group prior to/3 months after SG; LDA, linear discriminant analysis.
