CSF2 and melanoma: Using the same subpopulation of subjects (I/II melanoma patients), we fitted the entire data using the best classifier and the subset of features found previously (i.e., a LR classifier with the features Breslow thickness, GM‐CSF, IL‐4, and DCD), and we computed the optimal point on the ROC curve that corresponded in this case to FPR (1‐specificity) = 0.11 and TPR (sensitivity) = 0.79 (see panel A, Fig. 3).
