IL6 and susceptibility to pneumonia measurement: Analyses of the full data set failed to identify any significant association of pneumonia risk with the IL-6 gene -174C allele (OR = 1.00; 95% CI: 0.98–1.03), the IL-10 gene -592C allele (OR = 1.20; 95% CI: 0.95–1.52), or the IL-10 gene -1082A allele (OR = 1.21; 95% CI: 0.99–1.49).
