However, the association between PD-L1 expression and lymph node metastasis was marginally significant ( p = 0.058).
However, the association between PD-L1 expression and lymph node metastasis was marginally significant ( p = 0.058).
However, only lymph node invasion retained statistical significance in multivariate analysis ( p = 0.010) for OS, and PD-L1 positivity ( p = 0.079) only showed a trend toward significance without reaching statistical significance (Table 2 ).
When testing for the prognostic significance of PD-L1 for OS in multivariate analysis, the p -value did not reach statistical significance, likely due to the small number of PD-L1-positive cases.
