Table 2.
Statistically significant qEEG features beyond EC/EO tasks. Subject n and mean ± SEM spectral power are presented for each band and ratio (rows) with Wilcoxon rank sum test S (sum of the rank scores), Z scores, unadjusted p values (prob > |z|), and false discovery rate- (FDR-) adjusted p values. Significant differences and those surviving FDR correction are highlighted (bold).
