users and controls. Although there is no widely-accepted method to determine the significance of changes in QICu values, adding phase-locking measures clearly better-accounted for externalizing prediction because QICu values were smaller when phase-locking was used as a predictor of SUDs either alone (Table 1; 5/8 instances for delta, 8/8 for theta) or in conjunction with evoked energy (Table 2; 6/8 for delta, 8/8 for theta).
