Degree of statistical correlation between large surfactant aggregate protein and lyso-PC content and lung injury severity parameters

	Large aggregate total protein content		Large aggregate lyso-PC content
Lung injury parameters	r	P	r	P
BAL RBCs	0.894	<0.0001	0.847	<0.0001
BAL albumin	0.859	<0.0001	0.821	<0.0001
BAL total protein	0.906	<0.0001	0.894	<0.0001
BAL protein/phosphate	0.918	<0.0001	0.943	<0.0001
Lung MPO	0.763	<0.0001	0.865	<0.0001
BAL PMNs	0.737	<0.0001	0.837	<0.0001

Pair-wise correlations and significance values were determined for the indicated parameters of large aggregate composition and lung injury severity based on pooled data for uninjured controls, LC at 24, 48, 72, and 96 h, and CASP and LC + CASP at 24 h (n = 40 – 43 for each correlation with large aggregate total protein content and n = 26 – 28 for each correlation with lyso-PC content).
