Study summary

Primary objective:

To compare long-term glycemic control and preservation of beta cell function when basal insulin or sulfonylurea is added on metformin in the early Type 2 Diabetes Mellitus patients

Secondary objective:

To assess the change of insulin resistance, microvascular complication incidence, patient satisfaction with treatment
