GSTM1 and major depressive disorder: When focusing on the partially remitted MDD group (n = 17), we found significant negative correlations between mean [oxy-Hb] changes during VFT at T1 and changes in HRS-D scores from T1 to T2 in 10 channels (ch 20, 22, 23, 31, 32, 33, 35, 42, 51, 52; uncorrected P = 0.002 to 0.040); however, there were no significant channels with 52-channel FDR-correction.
