Median (IQR) biomarker levels in cases and controls.

1OR for bacterial pneumonia associated with a 1 IQR higher marker level after loge transformation; matched variables include age, smoking, baseline cART use and site of enrollment.2OR for bacterial pneumonia associated with a 1 IQR higher marker level after loge transformation adjusted for gender, race, HIV RNA, CD4+, prior AIDS, IDU and lipid lowering drugs (in addition to the matching variables age, smoking, baseline cART use and site of enrollment).AOR = adjusted odds ratio, CC16 = Club Cell Protein 16, CI = confidence interval, hsCRP = high sensitivity C-reactive protein, IL-6 = interleukin 6, OR = odds ratio, SP-D = surfactant protein D.
