HR = hazard ratio; CI = Confidence Interval; PTSD = posttraumatic stress disorder; BMI = body mass index; HD = heart disease.

a

HD mortality included myocardial infarction, chronic ischemic HD, atherosclerotic HD, heart failure, and hypertensive HD.

b

Models adjusted for theater status only.

c

Models concurrently adjusted for theater status, baseline age, intelligence, pack-years of smoking, and BMI >30.

d

Models concurrently adjusted for theater status, baseline age, intelligence, pack-years of smoking, BMI >30, and history of depression.

Variables assessed but deleted from models due to nonsignificance included: race, family history of HD, history of alcohol abuse/dependence, and history of antisocial personality disorder.
