In contrast, the Gehan-Breslow-Wilcoxon test did not reach statistical significance for either endpoint (RFS: χ2 = 2.385, df = 1, P = 0.1225; OS: χ2 = 2.745, df = 1, P = 0.0975).

The Log-rank test for trend yielded a P value close to 0.05, indicating a potential linear prognostic gradient that failed to reach significance owing to limited cohort size; accordingly, validation in larger patient series is required.
