ASCVD = atherosclerotic cardiovascular disease; CO = carbon monoxide; GSW = gunshot wound; MDD = major depressive disorder; MVC = motor vehicle crash; PMI = postmortem interval.
↵* In nonpsychiatric controls, the mean age was 42.08 ± 15.35 yr, mean PMI was 16.54 ± 6.56 h, and mean brain pH was 7.02 ± 0.15.
↵† In depressed individuals who died by suicide, the mean age was 38.96 ± 15.40 yr; mean PMI was 18.92 ± 6.02 h, and mean brain pH was 6.96 ± 0.25.
