ITT analysis, ANCOVA: means from immediate post-intervention, mean change difference and effect size. p-values are from the ANCOVA based on multiple imputation. A p-value < 0.05 was considered statistically significant
*Mean change difference from baseline to immediately post-intervention controlling for outcome measured at baseline
