Type XVIII collagen degradation products in acute lung injury

Table 1 Characteristics of acute lung injury and septic at-risk patients

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

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).
