Cluster analysis conducted separately on men and women revealed apparent similarities and differences between the sexes. The greatest similarity between the sexes appeared in the alpha-gamma domain (Fig. 2, Fig. 3A). All candidate clusters found in alpha-gamma domain showed greater PAC in the AUD groups, and significant alpha-gamma PAC clusters were seen in both men (M15, Fig. 2B) and women (W16, W17, Fig. 2B).
