Sex-Specific Prevalences, Odds Ratios, and 95% Confidence Intervals for the Association Between Episodic Migraine and Post-Traumatic Stress Disorder

	Women				Men
	No HA n (%)	Episodic Migraine n (%)	Model 1 OR (CI)	Model 2 OR (CI)	No HA n (%)	Episodic Migraine n (%)	Model 1 OR (CI)	Model 2 OR (CI)
PTSD Lifetime	141 (6.6)	42 (20.8)**	3.19 (2.14, 4.76)	2.77 (1.83, 4.21)	58 (2.6)	12 (24.5)**	10.14 (4.80, 21.40)	6.86 (3.11, 15.11)
PTSD 12 months	67 (3.1)	26 (12.9)**	3.82 (2.31, 6.32)	3.44 (2.03, 5.82)	27 (1.2)	10 (20.4)**	19.15 (8.13, 45.07)	19.70 (8.08, 48.05)

^**P < .001 as compared to those with no headache; Model 1 = OR (95% CI) adjusted for age, marital status, race, education, and smoking; Model 2 = OR (95% CI) adjusted for age, marital status, race, education and smoking and other DSM primary lifetime.

In addition to demographics, model 2 lifetime odds ratio are adjusted for other lifetime odds ratio of primary MDD, GAD, ETOH abuse and lifetime odds ratio of any drug abuse, while 12-month odds ratio are adjusted for 12-month odds ratio of primary MDD, GAD, ETOH abuse and 12-month odds ratio of any drug abuse.

Table modified from data from reference (3).

CI = confidence interval; DSM = Diagnostic and Statistical Manual; ETOH = alcohol; GAD = generalized anxiety disorder; HA = headache; MDD = major depressive disorder; OR = odds ratio; PTSD = post-traumatic stress disorder.
