Figure 1.

Partial plots from a random forest, illustrating the association between pulmonary vascular disease (PVD) and selected proteins (in relative fluorescent units) after averaging out the influence of the remaining proteins in the random forest. Large values for logit Pr (PVD) (y-axis) indicate higher probabilities for PVD, y-axis values below 0 indicate lower probabilities for PVD, and a 0 y-axis value indicates probabilities of 0.5 or no discrimination between PVD and no PVD. GP114 = G-protein–coupled receptor 114; MSP = macrophage-stimulating protein; NCK1 = noncatalytic region of tyrosine kinase adaptor protein 1.
