In the study published in 2016 by Alfadhli et al. [40] on 60 pregnant patients with GDM monitored by CGMS and 62 GDM patients monitored by SMBG in the CG, revealed that, although no statistically significant difference was obtained, the AUC for hyperglycaemia and hypoglycaemia were ameliorated in the last day compared to the first day of sensor wearing and the CGMS group necessitated lower doses of insulin (20.67 ± 18.03 vs. 29.83 ± 43.83 in the CG); there were no differences in the number of patients receiving insulin treatment between groups. The gene discussed is INS; the disease is Hypoglycemia.
