Tumor grade showed a trend toward significance (HR 1.58, 95% CI: 0.93; 2.67, p = 0.088) ( Figure 1 ; Table 2 ).
Tumor grade showed a trend toward significance (HR 1.58, 95% CI: 0.93; 2.67, p = 0.088) ( Figure 1 ; Table 2 ).
LVI and other variables did not reach statistical significance in the multivariable model ( Table 2 ).
Next, subgroup analyses, especially those of Nx patients, had a small sample size, which resulted in borderline significance of the analyses, most likely due to the limited statistical power.
