Comparative effectiveness of canagliflozin, SGLT2 inhibitors and non-SGLT2 inhibitors on the risk of hospitalization for heart failure and amputation in patients with type 2 diabetes mellitus: A real-world meta-analysis of 4 observational databases (OBSERVE-4D).

Aims Sodium glucose co‐transporter 2 inhibitors (SGLT2i) are indicated for treatment of type 2 diabetes mellitus (T2DM); some SGLT2i have reported cardiovascular benefit, and some have reported risk of below‐knee lower extremity (BKLE) amputation. This study examined the real‐world comparative effectiveness within the SGLT2i class and compared with non‐SGLT2i antihyperglycaemic agents.
