Randomization and Masking
Participants enrolled were randomly assigned to the MPGT or the TAU group in a 1:1 ratio using a preplanned randomization list. Raters were masked to the study group. Participants were masked to the study group and their pharmacogenomics report until the end of the trial. Clinicians who took care of participants in the MPGT group had access to the pharmacogenomics report to guide medication selection.
