¹Only complete cases were used. Some percentages may not sum to 100 due to rounding.

²Tests for differences between intervention and control were performed using Wald tests in hierarchical logistic regression models for binary variables and in hierarchical ordered logistic models for ordinal variables.

³There were 3,763 children interviewed, 1,147 only at baseline, 1,478 only at follow-up, and 1,138 at both time points.

⁵Due to missing data in the FitnessGram Passing Rate variable, the sample size for this analysis is 4,256.
