Primary Endpoints
Change in Glycated Haemoglobin (HbA1c)
Baseline (Week 0), Week 52

Change from baseline (week 0) to week 52 in HbA1c is presented. The outcome measure was evaluated based on the data from in study period, where all data from randomisation until last date of any of the following: 1) last direct participant-site contact; 2) participants who withdrew their informed consent; 3) last participant-investigator contact as defined by the investigator for participants who lost to follow-up (i.e. possibly an unscheduled phone visit); 4) death of participants who died before any of the above.
