Compared with the NGT group, the maternal plasma CTRP6 levels in the GDM group were significantly lower during the second trimester (psecond trimester = 0.0268) and third trimester (pthird trimester = 0.0010), but significantly higher at delivery (pdelivery = 0.0251) (Figure 2). Here, C1QTNF6 is linked to gestational diabetes.
