Figure 1

The graphs show 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 were constructed based on the identified cutoff values. Optimal cutoff values of age were identified as 61 years and 75 years on survival.
