^† Variables adjusted for in the three models testing the impact of group status were variables found significantly different at baseline between intervention group (IG) and control group (CG). These variables include school year, child’s age, mother‘s and father’s educational levels, crowding index, receiving assistance (food basket), household food insecurity status, and children’s anthropometric measures (HAZ).
