Incretin Effect in Women with Former Gestational Diabetes within a Short Period after Delivery

Table 2

Beta-cell function from OGTT (BC_OG) and IVGTT (BC_IV) and incretin effect (IE) in all fGDM and in the two subgroups of fGDM characterized by normal glucose tolerance (fGDM_NGT) and impaired glucose metabolism (fGDM_IGR), compared to women who had normal pregnancy (CNT).
