Kaplan-Meier estimates of survival for the two groups based on the prognostic index (the low prognostic index group (solid curves) and the high prognostic index group (dashed curves) for all patients (Panel A) and for each stratum by IPI Score (Panel B) in the validation set. The P-value in graph pertains to a two-sided log-rank test. The P-value for a stratified log-rank test is 0.0293.
