ANGPTL8 and gestational diabetes: While no statistical differences were detected in terms of age (P=0.195), duration of gestational days (P=0.071), BMI (P = 0.872), FFA (P=0.752), and TC (P=0.146) levels between groups, the maternal serum ANGPTL8 levels were significantly elevated in NGT or GDM group compared with the control group (P < 0.05; Supplementary Figure 1).
