Note. CI = confidence interval. Treatment groups are as follows: students who remained in a treatment condition for both years of the study (T-T), students who remained in a control condition for both years of the study (C-C), students who switched from a control to a treatment condition (C-T), and students who switched from a treatment to a control condition (T-C). Data were derived from a linear regression model with the C-C group as the referent.
