Metformin alters gut microbial richness in combined groups of Danes and Indians. Microbial richness was significantly reduced in metformin-treated T2D patients (n = 166), when compared to NG controls (n = 275) or metformin-naive T2D patients (n = 132). Microbial richness did not significantly differ between NG controls and metformin-naive T2D patients. These differences were not reproduced when looking at Shannon index. Danish and Indians samples were included in the analysis. NG, normoglycemic controls; T2D, type 2 diabetes
