Validation of three- and six-gene biomarkers. Previously published three-gene [20] and six-gene [13] prognostic biomarkers were validated in the Director's Challenge dataset [21]. (a, b) Each patient was classified into good (blue curves) or poor (red curves) prognosis groups using the three-gene (a) and six-gene (b) biomarker, which were visualized with Kaplan-Meier curves. Hazard ratios and P-values are from stage-adjusted Cox proportional hazard ratio modeling followed by the Wald test.
