  • The 4 waves were the randomization conditions of the study. The waves determined when a practice started receiving the 12-month intervention. Practices in Wave 1 started from the first quarter of 2016; wave 2 started from the second quarter of 2016, and so on. The four waves were reported separately because the starting and end dates were different.
