Smoking and Predictors of Pneumonia Among HIV-Infected Patients Receiving Care in the HAART Era

Table 3.: Multivariate Poisson Model Estimates of the Effect of Smoking on Pneumonia Incidence Rates in 300 HIV-Infected Patients Receiving Care Between January 1996 and September 1, 2005

Covariate^*	IRR	95 % CI	p-Value
Current smoker	1.77	0.98, 3.21	0.060
Age, per 10 year increase	0.62	0.41, 0.93	0.019
HIV RNA level, per 1 log₁₀ increase	1.96	1.64, 2.38	<0.001

^* All factors which vary over time were measured at a pneumonia event among those who had pneumonia and at the last clinic visit among those who did not experience pneumonia; IRR, incidence rate ratio; CI, confidence interval.
