Table 2 Effect of ICU-acquired infection on posthospital mortality in multivariable Cox regression model

From: Intensive care unit acquired infection has no impact on long-term survival or quality of life: a prospective cohort study

Factor HR 95% CI P
ICU-acquired infection 0.83 0.47–1.46 0.52
APACHE II score on admission 1.07 1.04–1.46 < 0.001
Presence of chronic disease 3.23 1.6–6.54 0.001
Hospital-acquired pneumonia 2.6 1.57–4.33 < 0.001
Surgical reason for admission 1.93 1.23–3.03 0.004
