Decreased serum oxytocin levels are associated with β-cell dysfunction in patients with gestational diabetes mellitus (GDM). (A) Serum oxytocin level in patients with gestational diabetes mellitus (GDM, n = 50) and healthy pregnant women (non-GDM, n = 59), ***P < 0.001. (B) Correlation between glucose-stimulated c-peptide release and the serum oxytocin level in non-GDM and GDM women. ns, not significant; ***P < 0.001. (C) Correlation between HOMA-β index and the serum oxytocin level in non-GDM and GDM women. ns, not significant; **P < 0.01.
