Results from this study8

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

Studies that did not test the peptide alone8

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 Liraglutide aloneObservational studyEfficacy outcome

    After posterior cervical fusion, pooled agonist use including liraglutide was linked to lower pseudarthrosis rates at all reported times.

    Summary
    Posterior postoperative pseudarthrosis rates were also significantly decreased in the GLP-1 agonist cohort versus the non-GLP-1 agonist cohort at 6-months (13.21% vs. 22.28%; P <0.001), 1-year (14.37% vs. 24.45%; P <0.001), and 2-years (16.87% vs. 24.43%; P <0.001).

    Patients prescribed liraglutide, pramlintide, tirzepatide, semaglutide, lixisenatide, or dulaglutide within 1 year of surgery were propensity matched to patients without GLP-1 agonist prescriptions.
