Novel Phenotypic Clusters of Youth-Onset Type 2 Diabetes Offer No Added Prognostic Value to Simple Clinical Measures
Authors' conclusion
Youth-onset type 2 diabetes can be characterized into reproducible clusters that demonstrate differential response to treatments and risk of complications. Nevertheless, cluster membership did not add clinical utility beyond simple clinical measures for predicting outcomes.
Study context
- Population
- Autoantibody-negative, clinician-diagnosed T2D before age 20 years in TODAY and SEARCHSEARCH 333
- Comparison
- Phenotypic clusters vs simple clinical measures for predicting treatment response and complications
Primary result
As reported in the abstract
- Three clusters with differential responses to therapies and risk of treatment failure in TODAY; YIDD-T2 had the highest rate of treatment failure regardless of treatment arm
- Simple clinical measures performed comparably or better than both clustering methods at predicting treatment response and complications
Further findings
Complications
- YIDD-T2 also had high rates of T2D complications
Novel clusters from routine clinical variables
- Three novel clusters with different rates of treatment failure
