  • Between group differences at post-measurement adjusted for baseline differences. Intervention group was coded with 1 (independent variable), baseline values were used as covariate, positive values indicate higher values in the intervention group. Negative values indicate lower values in the intervention group. Data are M (SD), regression coefficients or Cohen’s d.
