Multiple linear regression analysis revealed a significant correlation with serum NGAL levels and FINS (beta = 3.066, P=0.001), HOMA-IR (beta = −2.679, P=0.007), fasting plasma glucose of the third trimester (beta = 1.133, P=0.002), and neonatal birth weight (beta = 0.219, P=0.028) in women with GDM. This evidence concerns the gene LCN2 and gestational diabetes.
