Multivariate logistic regression for medical diagnoses associated with active hepatitis C.

Diagnosis	Univariate OR for HCV+ vs. HCV−	Multivariate logistic regression
		HCV+ vs. HCV−		Current smoker vs. Current non-smoker
		ORadj	95% CI	ORadj	95% CI
Emphysema*	2.60	2.14	0.92--5.01	7.81	5.40—11.3
Hypertension†	1.64	1.65	1.20—2.27	1.13	1.01—1.27
Stroke‡	1.79	1.80	0.82–3.94	2.33	1.90—2.85
Current depression§	4.21	2.47	1.69—3.60	2.63	2.28—3.05
Current excessive alcohol||	2.14	1.12	0.69—1.81	2.14	1.81—2.54

Note: HCV− =without active hepatitis C infection, HCV+=with active hepatitis C infection, OR=odds ratio, OR_adj=adjusted odds ratio, CI=confidence intervals

^*Older age and ethnicity/race were also associated with emphysema.

^†Older age and ethnicity/race were also associated with hypertension.

^‡Older age and ethnicity/race were also associated with stroke.

^§Older age, ethnicity/race, history of use of cocaine, heroin, or methamphetamine, and female gender were also associated with current depression.

^||Younger age, ethnicity/race, history of use of cocaine, heroin, or methamphetamine and male gender were also associated with excessive alcohol use.

Ethnicity/race associated with the highest rates of the specific medical diagnoses were: White for emphysema and excessive alcohol use, Black for hypertension and stroke, and Hispanic (not including Mexican-American) for current depression.
