SGLT-2 inhibitors are superior to GLP-1 receptor agonists for reducing hospital admissions for heart failure, while GLP-1 receptor agonists are superior for reducing non-fatal stroke.

Choose your diabetes drug based on your specific health history, not just blood sugar. If you have heart failure, an SGLT-2 inhibitor offers superior protection. If you have a history of stroke, a GLP-1 agonist is likely the better option. Ask your doctor which class aligns with your specific risks.

WeakQualifiesHIGH confidence
Notable differences were found between the two agents: SGLT-2 inhibitors reduced mortality and admission to hospital for heart failure more than GLP-1 receptor agonists, and GLP-1 receptor agonists reduced non-fatal stroke more than SGLT-2 inhibitors (which appeared to have no effect).

Why this rating

High certainty evidence for heart failure and moderate/high for stroke.
