FIGURE 1 Recursive partitioning and amalgamation–generated survival tree based on best stage for 17,726 cases. T and M stages (from proposed new T and M) are combined as 0/1 indicators. N stage is ordered. The number below each terminal node is the log hazard ratio, with the T1aN0M0 category as baseline.
