Allocation concealment and blinding
Allocation was concealed in order to avoid selection bias. Enrollment packets were placed in sealed opaque envelopes of equal size and thickness and locked in a drawer at the study site. Each envelope contained one paper denoting the random group assignment for each participant. Paper enrollment packets and data collection sheets were maintained to ensure reproducibility.The future PRACT and this feasibility study are single-blind studies; our outcome assessors were blinded to participant allocation. We have established a protocol where one research team member performs initial and final outcome assessments while a nurse obtains the randomization packet and performs the corresponding intervention.
