Randomization
TYPE 2 DIABETES
Eligible participants were randomly assigned (1:1) to either liraglutide, 3.0 mg (Novo Nordisk), or placebo (saline solution), via self-administered once daily subcutaneous injections with identical-appearing pens. All participants and clinical study personnel were blinded. Randomization was carried out by a computer-generated randomization sequence (Sealed Envelope) stratified by type of surgery (RYGB or SG) and type 2 diabetes status.
