The pregnant women with later onset of the GDM showed different associations, including negative correlation of genus Prevotella with cholesterol (r=-0.57; p=10-3) and genus Collinsella with CP-RI (r=-0.58; p=10-3) and positive correlation of genus Anaerostipes with CP-RI (r=0.61; p=5x10-4) and Escherichia/Shigella group with nonHDL (r=0.82; p=3x10-6), LDL (r=0.70; p=3x10-4) and triglycerides (r=0.67; p=6x10-4) levels. Here, CP is linked to gestational diabetes.
