Demographic and histological characteristics of the subjects

Control n = 17 Major depressive disorder n = 17
Age (years) 51.8 ± 3.4 51.5 ± 3.1 p = 0.950
Sex (M/F) 13/4 12/5 -
Postmortem interval (PMI; hours) 23.4 ± 1.5 24.4 ± 2.4 p = 0.811
Tissue pH 6.6 ± 0.1 6.4 ± 0.1 p = 0.119
Fixation time in formalin (weeks) 155 ± 21 127 ± 15 p = 0.290
