Results of the LEfSe analysis. A A distribution diagram of LDA score of different species. Length of histogram represents an influence of different species. Species with LDA score is higher than 4 can be regarded as biomarkers with statistical difference among groups. B A evolutionary branch diagram of different species. Circles radiating from inside to outside represent the classification hierarchy from phylum to species. Each small circle in different classification hierarchies represents a classification at this hierarchy. The diameter of the small circle is directly proportional to the relative abundance. Species with no significant difference are uniformly colored as yellow, whereas the species with significant difference which can be used as a biomarker for T2D are colored as red. The red node indicates the microbial flora that play an important role in the red group
