Arms Assigned Interventions
Active Comparator: Detemir + Met
Individually adjusted insulin detemir (Detemir) was given subcutaneoulsy (s.c.) at bedtime in the thigh at an initial dose of 0.1 U/kg once daily for 50 weeks in combination with 1000-2000 mg/day metformin (Met). Pending evaluation of HbA1c every 3 months, individually adjusted insulin aspart was added to the insulin detemir treatment (up to three doses daily for maximum 36 weeks, injected s.c. [under the skin]) if treatment target of HbA1c below 7.0% was not reached.
Drug: insulin detemir
Initial dose of 0.1 U/kg once daily, injected s.c. (under the skin).
Drug: insulin aspart
Pending evaluation of HbA1c every 3 months, insulin aspart was added to the insulin detemir treatment (up to three does daily, injected s.c. (under the skin)
Drug: metformin
1000-2000 mg/day in combination with insulin treatment
Active Comparator: BIAsp 30 + Met
Individually adjusted biphasic insulin aspart 30 (BIAsp 30) was given subcutaneously (s.c.) in the abdomen at dinner at an initial dose of 0.1 U/kg once daily for 50 weeks in combination with 1000-2000 mg/day metformin (Met). Pending evaluation of HbA1c every 3 months, the dose was intensified up to 3 doses daily, injected s.c. (under the skin) if treatment target of HbA1c below 7.0% was not reached.
