Figure 2.

a. Representative images of VSCC PD-L1 IHC expression results separated by scoring. Bar = 50 μm.

b. Table of PD-L1 IHC expression scores for VSCC. Expression ≥50 and <50 expression was compared to HPV-final consensus status using Fisher’s exact test with a p-value <0.05 considered significant.

c. Kaplan–Meier curves for overall survival by CPS and TPS expression levels of PD-L1 and compared by log-rank test with a p-value <0.05 considered significant.
