This finding was also observed in the literature data: a study by Kestilä et al. [59], on 36 pregnant patients with GDM monitored by CGMS and 37 patients monitored by SMBG, noticed a higher rate of antihyperglycemic drug therapy (insulin, metformin, or both) in the CGMS group compared to the CG (31% vs. 8%, p = 0.0149). Here, INS is linked to gestational diabetes.
