Table 2 Cox proportional hazard of acute lung injury free-survival through 28 days from hospital admission

From: Clinical review: Early treatment of acute lung injury - paradigm shift toward prevention and treatment prior to respiratory failure

Parameter Risk ratio 95% CI P-value
Antiplatelet therapy 0.34 0.13-0.88 0.03
Propensity for antiplatelet therapya 1.08 0.93-1.26 0.32
APACHE III at ICU hour 1 1.02 1.00-1.04 0.08
LIPS 1.67 1.33-2.12 <0.01
  1. aThe propensity for antiplatelet therapy was calculated based on a multivariate logistic regression analysis that included age, sex, coronary artery disease, diabetes mellitus, smoking, and prehospitalization statin therapy.
