Study Arms:
- Dapagliflozin add-on group (Type: ACTIVE_COMPARATOR): T2D subjects aged 20-80 years, presenting with HbA1C 7.1-9.0%, preserved kidney function (defined as estimated glomerular filtration rate (eGFR) \> 60 mL/min/1.73 m2), preserved LV function (defined as EF ≥ 50% by echocardiographic screening in the initial 2-week run-in period), and those treated with oral anti-diabetic drugs (except SGLT2i) and/or insulin therapy at least 3 months prior to the study were randomised to Dapagliflozin (10 mg/qd) add-on group.
- Standard of care (SOC) group (Type: ACTIVE_COMPARATOR): T2D subjects aged 20-80 years, presenting with HbA1C 7.1-9.0%, preserved kidney function (defined as estimated glomerular filtration rate (eGFR) \> 60 mL/min/1.73 m2), preserved LV function (defined as EF ≥ 50% by echocardiographic screening in the initial 2-week run-in period), and those treated with oral anti-diabetic drugs (except SGLT2i) and/or insulin therapy at least 3 months prior to the study were randomised to SOC treatment group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
