Table 4 Areas in which the perfusion of patients in the active tDCS group exceed that of those in the sham group exceeds at the first follow-up examination (F1), which was scheduled directly after the stimulation period (p < 0.001, cluster threshold k = 44; analysis corrected for age, disease duration (years), aura, and migraine days during the baseline period) (see Fig. 2B).
