  1. 01HumanNon-randomized trialEfficacy outcome

    In adults with obesity, once-weekly semaglutide gave a mean total weight loss of 11.3% at 12 months, significantly less than sleeve gastrectomy (28.6%).

    Summary
    SG achieved significantly greater weight loss at all time points. At 12 months, mean %TWL was 28.6% for SG versus 11.3% for semaglutide (p < 0.001).

    Semaglutide was administered for a planned duration of 24 weeks, after which continuation or discontinuation was determined by patient preference.
