This study investigates the association between semaglutide and these AE using the FDA Adverse Event Reporting System (FAERS). We conducted a disproportionality analysis using FAERS data.

Reporting Odds Ratios (ROR) and Proportional Reporting Ratios (PRR) were calculated to assess the association between GLP-1 receptor agonists and the AE. Semaglutide showed a significant ROR and PRR for NAION, suggesting a stronger association compared to other GLP-1 receptor agonists. The findings suggest a disproportionate reporting signal for semaglutide and NAION.
