In multiple logistic regression analysis (adjusting for maternal age, fetal sex, and GDM) of AGT rs3789678 and AGTR1 rs275645, only maternal age was significantly associated with GH (p < 0.0001, OR = 1.324, 95% CI: 1.165, 1.504) or PE (p < 0.0001, OR = 1.198, 95% CI: 1.101, 1.304). This evidence concerns the gene AGT and gestational diabetes.
