PAC (top four rows) and asymmetry (last two rows) indices. Theta, Alpha, Beta and Gamma results are presented from the left to right columns. In each figure, dots represent patients, with triangles indicating participants identified as outliers based on Cook's distance, and circles representing data included in the correlation coefficient calculation. The fitted line is provided with the corresponding correlation coefficient and p-value (red: significant p < 0.05, gray: non-significant).
