Fig. 1.
Relative risk (RR) for disease-free survival.
(A) Risk according to WBC. Figure 1A indicates the variation of the relative risk in the higher WBC as compared to the lower WBC population as a function of the WBC cut-off values. (B) Risk according to WBC index. Figure 1B indicates the variation of the relative risk in the higher WBC index as compared to the lower WBC index population as a function of the WBC index cut-off values. Dashed curves represent the lower limit of the 95% confidence interval. A dashed curve upon the WBC or WBC index axis indicates thus the statistical significance of the cut-off (significantly worsened DFS in patients with higher WBC or WBC index); G/L = 109/L.
