T-cell infiltration is higher in HPV+ HNSCC compared to HPV- and normal control counterparts. A previously reported 13 gene T-cell transcript signature was calculated for HPV+, HPV-, and matched normal-adjacent control tissues. Numbers in brackets refer to the number of samples included in each analysis. Statistical p value significance levels are indicated as follows: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001; ns—not significant
