Moreover, through the mimetic trajectory, we found the key nodes of EVT in GDM and PE during the mimetic process and performed BEAM analysis on them respectively, finding that BTG2 was the core gene at the branch in GDM, whereas INHBA was the core gene at the branch in PE, which further illustrated the core roles of BTG2 and INHBA in PE merged with GDM. Here, BTG2 is linked to gestational diabetes.
