MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There are several randomized controlled trials of Sodium-Glucose Cotransporter 2 Inhibitors (SGLT2i) but none (not a single study) provided a head-to-head comparison with sulfonylureas — the most commonly prescribed antihyperglycemics after metformin.
We resolved to leverage advanced methodologies to undertake a head-to-head investigation of the comparative effectiveness of SGLT2I vs sulfonylureas on the risk of all-cause mortality.
MedicalResearch.com: What should readers take away from your report?
Response: In people with diabetes already on metformin, initiation of SGLT2i was associated with lower risk of all-cause mortality compared with initiation of sulfonylureas.
This effect was evident regardless of cardiovascular disease status, regardless of albuminuria and eGFR.
Continued use of SGLT2i + metformin was superior to using SGLT2i alone (this is important as a lot of people are using SGLT2i alone and skipping metformin).
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: Clinical practice and guidelines should be informed by evidence. There is a tendency to skip metformin and jump into SGLT2i immediately. I think our results provide evidence that combined use of SGLT2i + metformin is better than SGLT2i alone. I think this area deserves more examination.
