<qa>  What is the mean blood glucose concentrations calculated by summing glucose values obtained at 0,30All patients will randomly be assigned to one of 3 medication treatment groups-- dapagliflozin-metformin DAP-MET; 5 mg DAP MET 1000 mg BID, metformin XR MET 1000 mg BID or dapagliflozin DAP 10 mg QD; all subjects will be allocated to one of these 3 groups based on computer-generated random numbers using a block randomization method. Oral glucose tolerance tests OGTTs with glucose G and insulin I measured at 0, 30, 60, and 120 after glucose load to assess diabetes, fasting FBG and mean blood glucose MBG concentrations, insulin resistance and pancreatic ß-cell function will be performed prior to randomization and at 20-24 weeks after full doses of study medications are reached. Mean blood glucose MBG concentrations will be calculated by summing glucose values obtained at 0,30,60 and 120 minutes during the OGTT and dividing by 4. At the initial lab evaluation, creatinine and calculated eGFR, TSH, and ß-hCG will be determined for study inclusion. Baseline blood samples will also be analyzed for lipid profiles and liver enzymes.
