Bold values highlight matrix elements below the p<0.05 threshold (corrected for 42 multiple comparisons), showing significant differences. For both data sets, typically mean and GMV values showed significant differences with other parameters, while ALFF, fALFF, and Hurst showed little difference among each other (excepting ALFF and fALFF for HU). Standard deviation showed significant differences with all parameters for HU, while differing significantly only with GMV for BNU.
