Cox regression analysis regarding variables on admission associated with in-hospital death.

Variable	p	HR	95% CI
Charlson-Age Index	0.000	1.276	1.183–1.377
Albumin <34 g/L	0.039	1.534	1.021–2.303
Lymphocytes ≤800/μL	0.001	1.961	1.321–2.910
Lactate dehydrogenase >250 U/L	0.010	2.507	1.245–5.046
Creatinine	0.044	1.196	1.005–1.423
q-SOFA ≥2	0.004	2.123	1.272–3.542

hs-CRP: high sensitivity C-reactive protein. q-SOFA: quick-Sequential Organ Failure score. HR: Hazard Ratio.

Variables such as CRP >8 mg/L (p = 0.232), male gender (p = 0.210) and bilateral infiltration (p = 0.086) were not independent predictors of mortality when entered in Cox regression model.
