Abstract
OBJECTIVE: To evaluate the effects of sibutramine (15 and 20 mg/day) on weight, metabolic control, and blood pressure in metformin-treated obese subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS: A 12-month randomized prospective placebo-controlled double-blind study was performed. It included 21 primary and secondary care centers in England, Canada, France, and Belgium. A total of 195 subjects (44% male) with type 2 diabetes and a BMI >27 kg/m(2) were studied. Changes were assessed in weight, blood pressure and resting heart rate, HbA(1c), fasting glucose, and lipids. RESULTS: Sibutramine induced significant weight loss (P < 0.001) with both 15 mg/day (5.5 +/- 0.6 kg at 12 months) and 20 mg/day (8.0 +/- 0.9 kg), whereas placebo did not (0.2 +/- 0.5 kg). Weight loss > or = 10% was achieved by 14 and 27% of subjects receiving 15 and 20 mg, respectively, but by none given placebo. Glycemic control improved in parallel with weight loss, and subjects who lost > or = 10% weight showed significant decreases in both HbA(1c) (1.2 +/- 0.4%, P < 0.0001) and fasting plasma glucose (1.8 mmol/l, P < 0.001). HDL cholesterol increased slightly with the higher dose, whereas plasma triglycerides fell with both doses, especially in subjects with weight loss of > or = 10% (a 29% decrease, P < 0.01). Treatment was generally well tolerated. Sibutramine treatment raised sitting diastolic blood pressure by > or = 5 mmHg in a higher proportion of patients than did placebo (43% with 15 mg/day vs. 25% with placebo, P < 0.05), but this effect was less evident in subjects who had a weight loss of > or = 10% weight. Pulse rate increased significantly more with sibutramine, being > or = 10 bpm higher in 42% of treated patients versus 17% with placebo (P < 0.01). CONCLUSIONS: Sibutramine can be an effective adjunct to metformin treatment in selected obese type 2 diabetic subjects and improves metabolic control in individuals who lose weight.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
