  1. There were missing values for some of the other measures used for comparison; the number of observations is presented in Table 3; p-values for differences in scores: * p < 0.003; ** p < 0.001; a |d| = effect size (Cohen´s d), large effect sizes (|d| ≥ 0.8) are printed bold. This analysis is based on baseline data.
