There are 2 models above, one for each group of youth (SEARCH type 1 and type 2 diabetes). A forward selection model was used, adding the most significant predictor with a p-value of 0.1 or less at each iteration. Predictors with cells shaded were not included in the final model for that particular group of individuals.

For the categorical variables, the reference groups are female and other race. NS= not significant
