Ln, natural logarithm; WBC, white blood cell; PT, prothrombin time; CRP, C-reactive protein; VEGF, Vascular endothelial growth factor; Ang-2, angiopoietin-2; SE, standard error; PaO₂, arterial oxygen tension.

Analysis using a mixed model to account for the random effect between subjects (logarithmic transformed VEGF and Ang-2 values were used).
