LGALS3 and gestational diabetes: GDM with the normal weight group had higher plasma galectin-3 levels (the first trimester: 7.47 vs. 6.89 ng/mL; P = 0.021 and second trimester: 7.61 vs. 6.88 ng/mL; P = 0.027) than the HP with the normal weight group, but there were no statistically significant differences in pre-pregnancy BMI between the two groups (Fig. 1C and D).
