Note: Generalized estimating equations with identity link and normal distribution were used in all models to adjust for clustering by family and were calculated using SAS PROC GENMOD. Beta coefficients were estimated in 8 separate regression models (one for each predictor). All models adjust for participant age, race, and sex. Boldface indicates statistical significance (***p ≤ 0.001, **p ≤ 0.01, *p ≤ 0.05, ~p ≤ 0.10). Multiple imputation results are from 10 imputed data sets.
