Spearman's correlation coefficients (rho) (two-tailed; in parentheses) are listed. Asterisks denote statistical significance (*p<0.05). Alpha and beta power showed a significant correlation with psychological but no physiological symptoms. The β/α ratio also showed significant rho only for psychological symptoms.
