Note. Interactions not involving the intervention (i.e., Poverty × Time) were included in analyses but are not presented in the table. ns = nonsignificant (removed from model).

Baseline covariate is value of outcome measured at study baseline (kindergarten) and group-centered within school.

Site main effect represented by two dummy indicators (Washington is reference site).
