Supplemental Figure 2. Analysis of laryngeal SCC patients' survival according to PD-L1 mRNA expression. Kaplan-Meier curves for the analysis of the prognostic significance of PD-L1 mRNA expression in (a, b) FFPE specimens (cohort I) for the (a) disease-free survival (DFS) and (b) overall survival (OS), and in (c, d) tissue specimens (cohort II) for the (c) DFS and (d) OS. The p values calculated by log-rank test.
