Table 2.

Correlations between arterial oxygenation (PaO2), dynamic lung compliance and bronchoalveolar lavage fluid (BALF) protein values in 3 groups of surfactant preparations, i.e. those with SP-B, those with SP-C and those with SP-B + SP-C peptides/proteins, estimated by linear regression analysis.

Surfactant N r P-value
PaO2 vs dynamic lung compliance
SP-B 50 0.296 0.037
SP-C 19 0.497 0.030
SP-B + SP-C 36 0.543 <0.001
PaO2 vs BALF protein
SP-B 50 −0.248 0.082
SP-C 19 −0.445 0.056
SP-B + SP-C 36 −0.633 <0.001
Dynamic lung compliance vs BALF protein
SP-B 50 0.624 <0.001
SP-C 19 −0.798 <0.001
