 The study found that simple and complex stratification approaches for type 2 diabetes have been used, but only complex stratification has produced reproducible subtypes associated with clinical outcomes. However, both approaches require higher evidence to support the premise that type 2 diabetes can be subclassified into clinically, meaningful subtypes. The study suggests that testing whether subtypes exist in more diverse ancestries and tailoring interventions to subtypes may improve outcomes.
