  1. VD = vascular depression; MD = major depression; rMT = resting motor threshold (%); CSP = cortical silent period (ms); CMCT = central motor conduction time (ms); CMCTF = central motor conduction time calculated with F-waves (ms); A ratio = amplitude ratio; F wave A = amplitude of F-waves (mV). Data are expressed as mean ± SD. * = p < 0.05.
