Note: Statistics from parametric tests are expressed in M = mean, SD = standard deviation, F. Statistics from non-parametric tests are expressed in Mdn = median, IQR = interquartile range (these are more appropriate statistics for non-parametric data), and χ 2. Bold p values represent a significant (p < 0.05) main effect of group. η 2 = partial eta squared values for the three group comparisons.
