Consort flow diagram of enrollment and randomization to CMBAS and HSMP. The ns analyzed and excluded reflect the PP analyses. “Analyzed” participants were those with ≥ 2 observations for the respective measure (i.e., used to estimate the change in the outcome). While the LMMs also included participants who had baseline data only, these data were used solely for the estimation of intercepts (see Additional file 1: Table S2 for ns with non-missing baseline observations).
