Figure 5 Kaplan-Meier two-year survival as a function of the simplified prognostic score in the population examined (p < 0.0001 [log-rank] across scores). These bars are centered at the mean prognostic score values of five subgroups (mean value and number of patients): 1) 46.5, n = 408; 2) 67.3, n = 506; 3) 82.9, n = 807; 4) 97.4, n = 1,161; and 5) 123.9, n = 1,902.
