Women with serum NGAL levels in the highest tertile as well as those with levels in the middle tertile had a higher risk of GDM than those with levels in the lowest tertile, with adjusted ORs of 4.513 (95% CI = 1.209-10.224) and 2.231 (95% CI = 0.814-6.217), respectively (Table 4). This evidence concerns the gene LCN2 and gestational diabetes.
