  1. Model 1 is age- and sex-adjusted. Model 2 is adjusted also for covariates that proved significantly different between patients with and without pneumonia at univariate analysis (i.e. dementia and provenience from a nursing home). The cut-off value of hs-CRP was set at 61 mg/L according to the Youden index applied to the ROC method
