Authors' conclusion

In KTRs with diabetes, SGLT2i therapy improved glycemic control without increased safety concerns compared to standard treatments. Both groups exhibited similar risks of significant kidney-related events and all-cause mortality. These findings provide crucial insights into the existing limited data concerning this vulnerable population, which faces elevated risks of renal complications and medication-related adverse effects. Ongoing randomized controlled trials will provide additional safety data for SGLT2i in KTRs.

As reported in the abstract

Observational data: associations, not effects.

Secondary outcomes

Glycemic control improved more significantly in SGLT2i users

Safety

UTI, diabetic ulcers, fractures, amputations, DKA, all-cause mortality

Other outcomes showed comparable or lower risks in SGLT2i users
