Each row of the table contains the feature name, group averages, and P value, for each statistical test which had a P < 0.05 before applying Bonfcrroni’s correction for multiple comparisons. No features had P < 0.05 after applying Bonfcrroni’s correction. T-tests were used for power spectral density features, and rank-sum tests were used for coherence and phase-amplitude coupling features.
