Why the study?
Youth-onset type 2 diabetes is highly heterogeneous, which complicates trial evaluation and necessitates individualized management.
Can a predictive model of HbA1c trajectories accurately generate patient-matched synthetic controls for youth-onset type 2 diabetes?
Population
699 youth in the TODAY study and 1,555 real-world youth from SEARCH and UC Health Data Warehouse
Comparison
Model development and simulation across weight and dietary scenarios
Design
Predictive modeling and simulation study using nonlinear mixed effects
Follow-up
Median 4.5 yr
Key result
Weight loss and low-carbohydrate intake scenarios in a predictive model reduced 1-year HbA1c by 0.2% compared to weight gain and high intake among youth with type 2 diabetes.

Can a predictive model of HbA1c trajectories accurately generate patient-matched synthetic controls for youth-onset type 2 diabetes?
p-value: p=<0.01
A nonlinear mixed effects model accurately predicts HbA1c progression in youth-onset type 2 diabetes, enabling the creation of synthetic controls for future trials and individualized management.
Yang et al. (2026) conducted an observational in Youth-onset type 2 diabetes (n=2,254). Weight loss and low-carbohydrate intake vs. Weight gain and high carbohydrate intake was evaluated on HbA1c progression (p=<0.01). Weight loss and low-carbohydrate intake scenarios in a predictive model reduced 1-year HbA1c by 0.2% compared to weight gain and high intake among youth with type 2 diabetes.
