Fig 1. Altered biodiversity of gut microbiota in the GDM groups in comparison with control group.

The groups of control (n=14), GDM_A1 (n=15), GDM_A2 (n=5) and GDM_Total (n=A1+A2=20) were described in the Methods. (A, B) The ecological diversity of gut microbiota in the control and GDM groups was measured by Shannon index and Simpson index. (C, D) The alpha-diversity, richness of gut microbiota, was determined by Chao1 index and Observed species index.
