DiabetologiaPublished Cohort study

Authors' conclusion

This analysis shows that non-adherence to cardiometabolic drug regimens is common in type 2 diabetes mellitus and negatively affects kidney and cardiovascular outcomes.

Main finding

As reported in the abstract

Observational data: associations, not effects.

Further findings

Cardiovascular outcome (composite of MI, stroke and cardiovascular death) with non-adherence to antiplatelet drugs · median (IQR) follow-up 5.10 (4.12-6.12) years
