The multivariable Fine and Gray model identified significant risk factors for 30-day infection-attributable death (sHRs with 95% confidence intervals): an increase in age by 10 years (1.14 [1.02–1.26]), presence of malignancy (1.54 [1.17–2.02]), liver cirrhosis (2.15 [1.56–2.97]), corticosteroid use (1.61 [1.19–2.17]), septic shock (3.28 [1.98–5.42]), elevated C-reactive protein (1.60 [1.19–2.14]), pneumonia (1.81 [1.21–2.72]), persistent bacteremia (1.73 [1.31–2.30]), and failure to remove the eradicable focus (2.40 [1.38–4.19]) or absence of an eradicable focus (1.49 [1.08–2.04]). This evidence concerns the gene CRP and susceptibility to pneumonia measurement.
