Results from this study4

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, the peptide was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking the peptide.

  1. 01HumanNot a test of Semaglutide aloneObservational studyEfficacy outcome

    In publicly insured adults with obesity and type 2 diabetes, pooled GLP-1 receptor agonist users (semaglutide or tirzepatide) lost 2.3% of body weight at 3 years versus 22.9% with bariatric surgery.

    In plain wordsIn publicly insured adults with obesity and diabetes, people on GLP-1 drugs lost far less weight at 3 years than people with bariatric surgery.

    Summary · context
    This was a retrospective, multicenter study of obese, type-2 diabetic patients (T2D) ≥ 18 years old, who initiated weekly injectable semaglutide or tirzepatide or underwent bariatric surgery between January 1st, 2018 to July 31st, 2024.
    Summary · context
    7667 patients were included for analysis (7200 GLP1-RA, 467 bariatric surgery).
