NOTE. Results presented as RR (95% CI). Model 1 accounts for variables shown along with predisposing factors including sex, law enforcement, educational attainment, head injury, and pre-WTC PTSD. Model 2 further accounts for trauma severity. Model 3 additionally accounts for contemporary health and health behaviors, baseline depressive symptoms, and having ever received treatment for PTSD.
