Quantitative variables are mean values, with standard deviation indicated in parentheses.

5HHT genotype, genotype on the serotonin transporter gene; BDI, Beck Depression Inventory; BDNF, brain-derived neurotrophic factor; CAPS, Clinician Administered PTSD Scale; F, female; L, long allele on the serotonin transporter gene; M, male; MVA, motor vehicle accident; S, short allele on the serotonin transporter gene.

The Met carrier group comprises those subjects with Val/Met or Met/Met genotypes.
