a trend toward significancep = 0.06
A post hoc Wilcoxon ranksum test yielded significant group differences in the SC of the SN ( p < 0.05; HC mean ± std: 0.079 ± 0.031 Hz, MDD mean ± std: 0.095 ± 0.024 Hz), and a trend toward significance in one of the visual networks (VIS_2; p = 0.06; HC mean ± std: 0.075 ± 0.028 Hz, MDD mean ± std: 0.061 ± 0.027 Hz).
