Figure 1 (A–C) The image show defining the optimal cutoff values of age via X-tile analysis. (A) The black dot indicates that optimal cutoff values of age have been identified. (B) A histogram and (C) Kaplan-Meier curve were constructed based on the identified cutoff values. Optimal cutoff values of age were identified as 64 years based on survival.
