Milk glucose was lower in women with GDM than those without GDM at both 1 month (−5.23 ± 2.22; p = 0.02) and 3 months (−5.70 ± 2.22; p = 0.01), and milk insulin was also lower in the GDM group at both time points (−0.38 ± 0.17; p = 0.03 and −0.53 ± 0.17; p = 0.003, respectively) (Table 2). This evidence concerns the gene INS and gestational diabetes.
