^aResults for univariate analysis of variance comparing the effect of the 5-HTTLPR multimarker genotype (for white participants only) on PTSD subscale symptom score after controlling for the degree of shooting exposure. The sample population was divided into 2 groups: those who were nterviewed 2 to 4 weeks postshooting and those who were interviewed more than 1 month postshooting.
