Kaplan-Meier curves for the identified prognostic genes. The Kaplan-Meier curves for overall survival illustrates the identified prognostic markers and the patient groups based on the classification of gene scenario. (A) LEF1, (B) SFRP2, (C) RUNX1, (D) PSMD2, (E) XPNPEP2, (F) PPARD, and (G) AXIN2. Significance for each prognostic marker is computed by comparing patients in the particular scenario versus patients in any other scenario (black line) using a univariate (log-rank test, indicated by the P-value), and multivariate analysis (Cox's proportional hazard ratio model, indicated by the adjusted P-value).
