Aim To determine whether intensified blood glucose control , with either sulphonylurea or insulin , reduces the risk of macrovascular or microvascular complications in type 2 diabetes. To determine the effect of aggressive blood pressure control . Study Population 3867 newly diagnosed type 2 diabetic patients who were asymptomatic after 3 months of diet ; fasting glucose 6.1–15 mmol/l (110–270 mg/dl) ; treat for 10 years .
