The P‐values in bold indicate a significance of < 0.05; Effect size (d) was computed according to the formula presented by Cohen. The minimum N refers to the equal number of subjects in each group we need to recruit to detect a significant change at the 0.05 level corresponding to a power of 0.8 and the effect sizes (d) we reported here.

Unless otherwise indicated, the data are given as the means ± standard deviation.
