These time–frequency windows are numbered for practical aim (i.e. TF-1…TF-11) and refer to the Fig. 3. The limits of the windows are described (x and y limits); the lower P values (P min) of these windows were extracted with corresponding T values, x and y (x_Pmin and y_Pmin), power value in each patient group and t-test directionality
