    GLP-1 receptor agonists are linked to increased gastrointestinal adverse events, with high odds for nausea, vomiting, and diarrhea.

  • 2

    Evidence suggests GLP-1 RAs may lower the odds of serious infections and respiratory disease, but findings are of low to moderate certainty.

  • 3

    Associations with other health outcomes, including fractures and dementia, did not meet high-credibility thresholds and remain exploratory.

  • 4

    Methodological concerns were noted, including lack of prespecified protocols and inconsistent definitions in adverse event reporting.

  • 5

    Current evidence on GLP-1 RAs is insufficient for definitive conclusions, highlighting the need for further research.
