Table 4. Cox proportional hazard model for factors associated with risk of AIDS or death event.

Characteristic	Adjusted HR (95% CI)	P-value
HBV Vaccine Responder vs. Non-responder	0.33 (0.22–0.52)	<0.001
HIV Controller vs Non-Controller	0.2 (0.03–1.45)	0.111
African-American vs Caucasian	1.04 (0.70–1.54)	0.845
Hispanic/Other vs Caucasian	0.88 (0.49–1.57)	0.662
Female vs Male	0.56 (0.30–1.04)	0.065
Age at Last Vaccination (Per 10 years)	1.04 (0.81–1.34)	0.759
Number of Vaccine Doses, ≥3 vs 1–2	0.88 (0.61–1.28)	0.498
CD4 Count at Last Vaccination (For Every 100 Cells/uL)	0.80 (0.69–0.93)	0.003
Nadir CD4 Count Prior to Last Vaccination (For every 100 Cells/uL)	1.12 (0.94–1.34)	0.213
AIDS Before Last Vaccination	1.43 (0.9–2.29)	0.134

HR, hazard ratio; CI, confidence interval; HBV, hepatitis B virus; AIDS, acquired immunodeficiency syndrome.

Model stratified by era of HIV diagnosis (before or after 1996).
