^aThe intention-to-treat analysis was conducted using the Markov chain Monte Carlo simulation imputation. Generalized estimating equations were used to examine the effectiveness of the MBC program on primary outcomes. Pairwise comparisons were conducted with Bonferroni adjustment.

^bAll P values for pairwise comparisons were Bonferroni-adjusted.

^cCohen d was calculated by dividing the adjusted mean difference by the pooled unadjusted standard deviation at baseline [58].

^dAn increase implies worsening and a decrease implies improvement.
