3 Figure E1 The multivariate classification algorithm using the 5 highest-ranked biomarkers. A, The area under the curve was calculated for the final selected algorithm. B, The 249 samples were distinctly classified using the algorithm. Scores closer to 0 are normal and scores closer to 1 are malignant on the y axis. NSCLC, Non–small cell lung cancer; RF, Random forest; SVM, support vector machine; LDA, linear discriminant analysis; LRM, logistic regression; AUC, area under the curve.

4 Figure E2 The partial dependence plot using the 5 highest-ranked biomarkers. A1AT, CYFRA 21-1, IGF-1, and AFP increased likelihood of cancer with higher serum concentrations while RANTES decreased. A1AT, Alpha-1 antitrypsin; CYFRA, cytokeratin fragment; IGF, insulin-like growth factor; AFP, alpha-fetoprotein.
