  1. Study Completers were called only those participants, who completed therapy and produced MEG data sets (pre and post) of good quality that could be included in the final analysis.
  2. Note: For pair-wise group comparisons of continuous variables, Mann-Whitney U T ests were used; differences of categorical variables were evaluated by applying χ2-Tests for independence.
