Note: Model 1 is unadjusted. Model 2 is adjusted for covariates: age, type 1 diabetes duration, race, mode of insulin delivery, and sleep apnea risk. B is the unstandardized coefficient regression coefficient. SE standard error. β is the standardized regression coefficient. R² = coefficient of determination shown for each model. F² = Cohen’s f² effect size.
