From the investigated models, the combination of the expression of IL8, IL13, and TNFA (LR test p = 0.0002, cross-validation AUC 0.800, 95% CI 0.5844–1.000) was the strongest predictor of development of AGT at 1-year postpartum among the GDM women (Table 7). This evidence concerns the gene IL13 and gestational diabetes.
