ITLN1 and gestational diabetes: Normoglycemic obese mothers (7.1 ± 0.9 ng/mL) had significantly lower plasma omentin levels in comparison to normoglycemic mothers with normal weight (19.5 ± 2.3 ng/mL) and similarly obese women with GDM (8.2 ± 1.2 ng/mL) in comparison to the GDM-non-obese cohort (12.1 ± 1.4 ng/mL).
