Table 4 Logistic regression analysis of mortality risk factors in the ICU, hospital and 30 days after hospital discharge

From: The safety of beta-blocker use in chronic obstructive pulmonary disease patients with respiratory failure in the intensive care unit

ICU mortality risk factors
  Odds ratio Confidence interval 95% p
Septic shock in the ICU 7.49 2.43–23.14 0.001
PaO2/FiO2 on admission to the ICU 0.99 0.98–0.99 0.001
Beta-blocker use 1.14 0.52–2–49 0.75
Hospital mortality risk factors
Septic shock in the ICU 6.29 2.03–19.49 0.001
Hypertension 2.94 1.05–8.23 0.040
NIV in the ICU 0.21 0.08–0.57 0.002
PaO2/FiO2 on admission to the ICU 0.99 0.98–0.99 0.010
Beta-blocker use 0.98 0.46–2.06 0.95
30 days mortality risk factors
pH on admission to the ICU 0.71 0.63–0.79 0.001
Ischemic cardiac disease 4.77 1.49–15.24 0.009
Beta-blocker use 2.03 0.81–5.04 0.13
