  1. The ten most discriminating parameters according to the Fisher (F-) coefficient and their corresponding Wilcoxon test p-values are calculated between hemispheres in the cerebral white matter in the level of corona radiata (level 2) for both patients and controls.
  2. Correlat, correlation; DiffVarnc, difference variance; AngScMom, angular second moment; Teta, vectors of autoregressive model; SumAverg, sum average; InvDfMom, inverse difference moment; SumVarnc, sum variance; DifEntrp, difference entropy; WavEnLH, energy of wavelet coefficients in subband LH.
  3. * p-values of under 0.05 are considered statistically significant
