Analyses were mixed-effects linear regression models using the ITT sample. This sample was comprised of participants who completed at least one follow-up assessment

These analyses assessed the change from the post-treatment assessment (at 6 months from baseline) through the follow up assessments (at 9 and 12 months from baseline)
