  1. The mean scores of each measure are displayed for each training group are displayed with standard deviations in parentheses. Mean within-group change scores are displayed with 95% confidence intervals computed from non-parametric tests. Effect sizes (r) for the group x time interaction are displayed in the rightmost column. For primary measures, effects that are significant at p < .05, corrected for multiple comparisons are in bold. Exploratory measure effects that are significant at an uncorrected p < .05 are displayed in bold
