Mean rate of sustainability by month of study and intervention group. High intensity, high frequency (), high intensity, low frequency (); low intensity, high frequency (); low intensity, low frequency (). The mean rates of adoption were estimated from a linear mixed model that included eight factors, a random intercept, and an unstructured covariance structure. The mean rate of sustainability in the combined high intensity, high frequency group diverged shortly after randomization, yielding a statistically significant difference among the groups as early as 4 months. At the end of 12 months, the mean rate of adoption in the high intensity, high frequency group was approximately twice as high than in the other three groups combined (64.1 versus 37.8 per 100 opportunities, p < 0.001), which were not significantly different from each other (p = 0.34), and their rates of sustainability remained relatively constant over the duration of the trial
