From: Type XVIII collagen degradation products in acute lung injury

Characteristic ALI At risk for ALI P value 95% confidence interval
PaO2:FiO2 ratio 130 (40) 255 (92) 0.001 75 to 167
Lung injury score 2.6 (0.4) 1.2 (0.3) 0.001 1.0 to 1.5
APACHE II 24.5 (8.2) 21.7 (8.9) 0.294 2.5 to 8.2
SAPS II 57.4 (17.5) 54.8 (12.8) 0.631 -8.3 to 13.5
SOFA score 8.9 (2.8) 6.6 (4.3) 0.116 -0.8 to 5.5
  1. ALI = acute lung injury; APACHE = acute physiology and chronic health evaluation; FiO2 = fraction of inspired oxygen; PaO2 = partial pressure of arterial oxygen; SAPS = simplified acute physiology score; SOFA = sequential organ failure assessment. Data are expressed as mean (standard deviation).
