To the Editor: In their randomized controlled trial, Dr Dixon and colleagues1 compared adjustable gastric banding vs conventional therapy for type 2 diabetes. The authors observed that participants randomized to surgical therapy were more likely to achieve remission of type 2 diabetes compared with those who were assigned to conventional therapy. They concluded that magnitude of weight loss was the primary determinant of diabetes remission.
