Note: Year 3 site N = 28; CHOICE Adherence rating N = 394. Upper table values are regression coefficient estimates with confidence intervals, test statistics, and effect size estimates. Lower table values are descriptive frequencies with exact test p values and effect size estimates.

^*Statistically significant after false discovery rate correction, adjusted ps < .05.
