Are glucagon-like peptide-1 receptor agonists (GLP-1 RAs) associated with improved limb, cardiovascular, and kidney outcomes compared with dipeptidyl peptidase-4 (DPP-4) inhibitors in patients with diabetes and prior major adverse limb events?In this cohort study of 17 288 patients, the use of GLP-1 RAs was associated with significantly lower risks of limb events, amputation, cardiovascular events, progression to dialysis, and all-cause mortality compared with DPP-4 inhibitors.These findings suggest that GLP-1 RAs may offer important protective benefits for high-risk patients with diabetes and prior limb events, supporting their preferential use in secondary prevention.
