Patients with high PT levels showed a significant trend toward poor RFS compared with that of patients with low PT levels (P = 0.0151, Kaplan–Meier method) ( Table 5 , Figure 2 ).
Patients with high PT levels showed a significant trend toward poor RFS compared with that of patients with low PT levels (P = 0.0151, Kaplan–Meier method) ( Table 5 , Figure 2 ).
A highly significant association was observed between high PT level and shortened OS (P = 0.0373) and worse RFS (P = 0.0151).
