Validation of expression profiles by a third dataset. All 286 Veridex patients or 209 ER-positive patients were classified based on two previously derived expression profiles (Rosetta and Combined). The Kaplan-Meier survival curves corresponded to half of the patients who had SEP scores higher (green) or lower (red) than the median of all 286 scores. The contingency table, accuracy, and ROC curve area listed with plot were obtained after the Veridex patients were classified according to their 3-year prognosis as training patients.
