SEM: standard error of the mean; COGSTAT: a composite measure of cognitive impairment. The means and SEMs of each of the changes in the measures were calculated from the differences in the measure (Post − Pre) that were adjusted for age, sex, and the Pre (baseline) score of the measure. The P values for each group show the significance of the improvements (Post − Pre > 0) obtained from the Wilcoxon signed-rank tests (one-sided) and corrected by the Benjamini–Hochberg (BH) procedure to control the false discovery rate (FDR). The P values for each pair of the groups were from the Wilcoxon rank-sum test (two-sided), which explored the significant group differences in the improvements of each measure with a correction for multiple comparisons with the BH procedure in order to control the FDR. |
