 Number of hypoglycaemia events
  • Percentage of HbA1c value in target (%)

The difference in the percentage of HbA1 in range (<7%) tested at week 14 and 26 adjusted for baseline
  • Frequency of using FGM (times/day)†

Time frame: 24 weeks (from week 2 to week 26)
  • Frequency of using SMBG (times/day)

Time frame: 24 weeks (from week 2 to week 26)
  • Total of daily insulin dose (IU/kg/day)

The difference in insulin dose collected at week 14 and 26 adjusted for baseline
  • Questionnaires

The difference in scores of respective questionnaires collected at week 14 and 26 adjusted for baseline
 DDS
 HFS
 EQ-5D-5L

*CGM metrics analysed here are calculated with the sensor data from Ipro2.

†The frequency of using FGM is calculated with the recordings derived from the FGM system.

CGM, continuous glucose monitoring; CV, coefficient of variation; DDS, Diabetes Distress Scale; EQ-5D-5L, European Quality of Life Scale; FGM, flash glucose monitoring; HBGI, high blood glucose index; HFS, Hypoglycemia Fear Scale; LBGI, low blood glucose index; MAGE, mean amplitude of glucose excursion; MODD, mean of daily differences; SMBG, self-monitoring of blood glucose; TAR, time above range; TBR, time below range; TIR, time spent in range; TIT, time spent in target.
