Effect size and post hoc power estimation
An Jacob Cohen defined As means, we inputted to the formula the mean increment and decrement of DC strength over the detected functional pairs tabulated in Table Topological layouts of increased (red) and decreased (blue) rsFC between pairs of ROIs in the AAL space for every intervention group comparing the baseline and the follow-up conditions. An interested reader can read this figure in conjunction with STable Suppose the baseline and follow-up conditions are “A” and “B,” and we collect a sample from both scanning periods, i.e., we have two samples. We perform a two-sample test to determine whether the mean in group A, We computed the post hoc power according for a 2-sample 2-sided test adopting the equations reported in Chow et al. [The post hoc power was estimated by the following set of equations:
