GLP-1 RA initiation versus metformin and risk of cardiomyopathy in patients with cancer and diabetes treated with chemotherapy, radiation, or immunotherapy: a target trial emulation
Authors' conclusion
GLP-1 RA initiation was associated with a lower risk of cardiomyopathy compared with metformin among patients with cancer and T2D, supporting a potential role for GLP-1 RA in cardio-oncology prevention strategies.
