Figure 3. Kaplan-Meier curves showing disease free patient survival depending on TSCC HPV status and TILs, and n denotes the number of patients in each stratified group.

A) HPV⁺TSCC and B) HPV⁻TSCC patients stratified by the number of CD8⁺ TILs. High and low denotes CD8⁺ TIL count above and below the median values of 33 for HPV⁺TSCC and 4.4 HPV⁻TSCC. C) HPV⁺TSCC and D) HPV⁻TSCC patients stratified by the ratio of CD8⁺/FoxP3⁺ cell ratio. High and low denotes CD8⁺/FoxP3⁺ cell ratio above and below 1.
