Effect of Sibutramine on Weight Management and Metabolic Control in Type 2 Diabetes: A meta-analysis of clinical studies

OBJECTIVE - The aim of this study was to provide a comprehensive meta-analysis of randomized controlled clinical studies on the effects of sibutramine on weight loss and glycemic control in obese subjects with type 2 diabetes.
