Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75.
[Auto, unreviewed; quoted from abstract conclusions] In nationwide cohorts of patients treated for T2DM or obesity, initiation of GLP-1 RA was not associated with an elevated risk of VAR events. Despite a proposed argumentation of vagal activity, GLP-1 RA use was not associated with an increased risk in real-life users.

Abstract
[BACKGROUND AND AIMS] Glucagon-like peptide-1 receptor agonists (GLP-1 RA) carry side-effects such as dizziness and nausea related to increased vagal tone. This study investigated associations between GLP-1 RA use and the risk of vagal activity related (VAR) events. [METHODS] Using the Danish health registers, patients with type 2 diabetes mellitus (T2DM) first-time initiated on GLP-1 RA (exposure) or SGLT-2i (active control) were identified between January 2010 and October 2022. Standardized 1-year absolute risks of VAR events (syncope, fractures, bradyarrhythmia, or cardiac device implantation) were computed to compare risk associated with GLP-1 RA and SGLT-2i initiation. Complementary analyses in patients treated for obesity were performed as well. [RESULTS] During the study period, 50 076 and 73 138 patients with T2DM were initiated on GLP-1 RA (47% women, median age: 59 years [IQR: 50-68]) or SGLT-2i (39% women, median age: 64 years [IQR: 55-72]). Comorbidity was equally prevalent. The standardized 1-year absolute risk of syncope was 0.58% (95% CI: 0.51%-0.66%) among patients initiated on GLP-1 RA and comparable to patients initiated on SGLT-2i (0.56% [95% CI: 0.50%-0.62%]). 1-year risks of fractures, bradyarrhythmia, and cardiac device implantation were equally low and with corresponding standardized risk ratios of 0.90 (95% CI: 0.79-1.01), 0.97 (95% CI: 0.67-1.28), and 0.86 (95% CI: 0.62-1.10), respectively. No associations were found in the group treated for obesity either. [CONCLUSIONS] In nationwide cohorts of patients treated for T2DM or obesity, initiation of GLP-1 RA was not associated with an elevated risk of VAR events. Despite a proposed argumentation of vagal activity, GLP-1 RA use was not associated with an increased risk in real-life users.
