RF models. (A,B) Classification power (AUC) of RF models. RFs were trained with a progressively reduced number of genes to identify an optimal subset of genes corresponding to the proposed signature, for men and women, established by the second step of RFE strategy. Maximal AUC is indicated by a vertical dotted red line. (C) Number of genes composing men (blue), women (red), and all patients’ (yellow) RF‐based signatures.
