The MW test is used. The sign ‘✓’ indicates the presence of the peak in the corresponding features. This table shows in particular that the largest peaks are not the most statistically significant (discriminative) ones. The significance order summarizes the table. The ‘CPT significance order’ is calculated by the CPT software.
