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 |
| Storage time in ethanol (days) | 157 ± 25 | 117 ± 21 | p = 0.258 |
Values are means ± S.E.M.. Demographic and histological characteristics did not statistically differ between control subjects and those with major depressive disorder.
