Table 5

Multivariable hazard ratios and 95% confidence intervals of influenza vaccination and beta-blocker for hospitalization due to HF.

Influenza vaccine	Beta-blocker	HR	95% CI	P value
No	No	Reference
No	Yes	1.29	0.27–6.16	0.750
Yes	No	2.46	0.40–15.22	0.334
Yes	Yes	0.05	0.01–0.71	0.027

Note. All analyses were adjusted for gender, dyslipidemia, SCr, and LVEF, which are independent prognostic indicators for hospitalization due to HF.
