  1. CCA complete case analyses; MI multiple imputation; FRL free and reduced school lunch; Nat. Amer Native American; Pac Island Pacific Islander
  2. MI analyses is required for all clinical trials and CCA is what is more commonly reported, therefore, both MI and CCA are reported here
  3. a Weighted mean and standard error (SE) of each variable. Weighted refers to the total number of children within each school
  4. **Generalized linear mixed models (GLMM) with linear link was used to compute p-values of the continuous variables, GLLM with cumulative logit link was used to compute p-values of the categorical variables
