Standard CGM metrics
After the 3-day blood glucose monitoring period, CGM metrics were calculated. Metrics for each patient in day 2 were used for quantification of glycemic variability (GV). The mean of daily differences (MODD) calculation is based on the data of 2 integrated consecutive days (day 2 and day 3). The time in range (TIR) was defined as the percentage of time within the target glucose range of 3.3–7.8 mmol/L during a 24-h period. The time above range (TAR) and time below range (TBR) were above the target glucose range of 7.8 mmol/L and below the target glucose range of 3.3 mmol/L, respectively. GV parameters included the standard deviation (SD) of sensor glucose values, the glucose coefficient of variation (CV), the large amplitude of glycemic excursions (LAGE), the mean amplitude of glycemic excursions (MAGE), MODD and the postprandial glucose excursion (PPGE) (
