Statistical Analysis
Feasibility outcomes were compared across groups using the Fisher exact test (categorical variables) or the Wilcoxon test (ordinal variables). Secondary outcomes that are continuously distributed and measured at baseline and after treatment were analyzed with analysis of covariance (ANCOVA) using a generalized linear model in which the change in response to treatment (posttreatment minus baseline) is the dependent variable and baseline is the covariate. The adjusted treatment effect was calculated by subtracting the least-squares mean change between baseline and posttreatment data for MoveTrain minus JtMob from the ANCOVA, to assess the between-group difference in change in response for treatment after adjusting for baseline. When data were not normally distributed, nonparametric ANCOVAFor continuous outcomes,
