the AUD (M [S.E.M] = −0.077 [7.986]; P = 0.005) and HC (M [S.E.M.] = −0.088 [8.015]; P < 0.001) groups. Also, the IGD group (M [S.E.M.] = 0.135 [7.844]) exhibited marginal tendency of greater coherence in the beta band than the AUD group (M [S.E.M.] = 0.019 [7.835]; P = 0.023).There were no significant group or group × region effects for the delta, theta, or alpha bands (all P-values > 0.0167) and no significant group × region effects for the beta or gamma bands (all P-values > 0.0167).
