  1. Abbreviations: HSL Healthy Summer Learners, 21C 21st Century Program, HR hypothesized relationship, HS hypothesized support (i.e., did the relationship support the hypothesis), I-I intra-individual; estimates are based on multilevel mixed effects linear regressions with days nested within children, all estimates represent combined data from schools 1 and 2 (i.e., summer 2018 and 2019); bolded values indicated a statistically significant difference at p < 0.05. Support indicates statistically significant difference in the hypothesized direction or no statistically significant difference when no difference was hypothesized, Null indicates no statistically significant difference despite a hypothesis that the means should differ, and Conflict indicates a statistically significant difference that is contrary to the hypothesized relationship. 0 indicates no significant difference
