Multivariate Time-Dependent Cox Proportional Hazards Models for Association Between (A) Bloodstream Infection and Mortality, and (B) Ventilator-Associated Pneumonia and Mortality

Variable	Hazard Ratio (95% CI)
(A)
Bloodstream infection	1.14 (0.63–2.06)
Age	1.02 (0.99–1.05)
Administration of dexamethasone	0.69 (0.31–1.53)
Administration of tocilizumab	1.29 (0.74–2.24)
New renal replacement therapy	1.03 (0.62–1.70)
(B)
Ventilator-associated pneumonia	1.42 (0.83–2.45)
Age	1.02 (0.99–1.05)
Administration of dexamethasone	1.25 (0.72–2.18)
Administration of tocilizumab	0.71 (0.32–1.60)
New renal replacement therapy	0.99 (0.60–1.63)
