Conclusions:
GLP-1RAs was associated with an increased incidence of breast cancer compared to other antidiabetic regimens in patients with T2DM in a long-term observation. Acting on identical pathway, GLP-1RAs may show a blunt effect versus DPP4i in obese patients. The study is empowered by an enormous sample size in Epic Cosmos. Future improvements include stratifying exposure levels and stringently matching confounders.
