According to recent guidelines, individuals with type 1 diabetes should spend <4.0% of time per day glucose levels <3.9 mmol/L (<70 mg/dL) and <1.0% <3.0 (<54 mg/dL).In the GOLD randomized crossover trial, 161 treated multiple daily insulin injections (MDI) were continuous monitoring (CGM) or conventional therapy self-monitoring blood (SMBG) evaluated over 16 months. We estimated association between spent in hypoglycemia various mean HbA1c levels.Time (<3.9 mmol/L) increased significantly...
