ITT protocol violations shown in square brackets. Excludes one survey returned with no measures completed. Two types of protocol violations are shown (PV1) surveys completed outside the specified ITT periods, and (PV2) surveys received from practices not matching their planned ITT intervention status. For example, at time T1, the ITT schedule required step 1 practices to be post-intervention; however, there were 15 surveys received from practices not yet in receipt of the intervention.
