Outcomes
Primary Outcome Measures
Change From Baseline in A1C at Week 32
A1C is measured as a percent. Thus this change from baseline reflects the Week 32 A1C percent minus the baseline A1C percent
Secondary Outcome Measures
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 1
Change from baseline reflects the Week 1 FPG minus the baseline FPG. At Week 1, the dose was 50/500 mg b.i.d. for Sita/Met FDC and 30 mg q.d. for pioglitazone
Change From Baseline in 2-hour Post-Meal Glucose (PMG) at Week 32
Change from baseline reflects the Week 32 2-hour PMG minus the baseline 2-hour PMG
Change From Baseline in FPG at Week 32
Change from baseline reflects the Week 32 FPG minus the baseline FPG
Percent of Participants With A1C <7.0% at Week 32
