Authors' conclusion

In people with type 2 diabetes, the cardiovascular and kidney benefits of GLP-1 receptor agonists are consistent regardless of SGLT2 inhibitor use.

Study context

Population
T2DM; subgroups with and without SGLT2 inhibitor at baseline
Participants
17,072 participants · 3 trials
Comparison
GLP-1 receptor agonists vs placebo, by baseline SGLT2 inhibitor use
Outcome
MACE (nonfatal MI, stroke or CV death) and hospitalization for HF

Pooled result
