PRO questionnaire (SF-36v2™) measured the HRQoL which contains 36 items covering 8 domains of physical and mental health status. The raw scale scores from the SF-36 were transformed to a 0-100 scale scores (where higher scores indicated a better health status) which is further converted to norm-based scores using a T-score transformation in order to obtain a direct interpretation in relation to the distribution of the scores in the 2009 reference population . The total/overall (SF-36v2™) scores for physical and mental health from baseline to week 26 are presented here.
- Change From Baseline in Patient Reported Outcomes (PROs) After 26 Weeks: Summary Scores of Treatment Related Impact Measure for Diabetes (TRIM-D) [ Time Frame: After 26 weeks ]The patient reported outcomes are calculated based on TRIM-D questionnaire. The TRIM-D questionnaire consists of 5 sub-domains (treatment burden, daily life, diabetes management, compliance and psychological health), where each question is scored to a 1-5-point scale with a higher score indicating a better health state (less negative impact). Mean TRIM-D domain scores and the total scores are later transformed to a 0-100 scale for analysis. Summary scores from baseline and week 26 for total/overall scores are presented here.
