2.2. Randomization, Blinding, and Crossover
SECONDARY
Participants were randomly assigned to either interview with artificial intelligence-based system assistance for the medical history or the usual interview, at a 1:1 ratio, using a computer-generated random sequence. This sequence was created by a statistical analysis team member not involved in the statistical analyses of this study. Due to the study design, participants and simulated patients could not be blinded. The primary and secondary outcomes were crossed over and investigated in each group.
