Subjects who completed the 6-week Lead-in Period and who were randomized and dispensed sibutramine during the Treatment Period and continued standard care for weight management. If sibutramine was prematurely discontinued, subjects continued standard care for weight management during the Follow-up Period.

Subjects with a history of type 2 DM with at least one other risk factor (i.e., hypertension controlled on medication, dyslipidemia, current cigarette smoking, diabetic nephropathy with evidence of microalbuminuria), but no history of coronary artery disease, cerebrovascular disease, or peripheral arterial occlusive disease who completed the 6-week Lead-in Period and who were randomized and dispensed sibutramine during the Treatment Period and continued standard care for weight management.

For the sample size calculation, a two-tailed alpha level of 0.05 was used along with power of 90%. The annual composite event rate in the placebo arm was assumed to be 7.0%. A sample of 3983 subjects in each of the 2 groups, corrected for a 30% noncompliance rate (15% in Year 1 and 6.3% in each year, Years 2 to 4), followed for at least 3 years was expected to have 90% power to detect a relative risk reduction of 15% with sibutramine relative to placebo.

No adjustment for multiple testing or interim analysis was performed. The primary outcome was tested at a 2-sided alpha level of 0.05.

The Cox model included factors for treatment, country, gender, and age (continuous) at Lead-in Period baseline. For the calculation of risk, the sibutramine arm is the numerator and the placebo arm is the denominator.
