Relationships among PD-L1, TMB, PD-1⁺ Tils, CD8⁺ T cell, and response to anti-PD-1 therapy. a Heatmap result of the PD-L1 expression, TMB, PD-1⁺ Tils infiltration, and CD8⁺ T cell infiltration in different groups according to the response to anti-PD-1 therapy. b–e Differences in PD-L1 expression, TMB, PD-1⁺ Tils infiltration, and CD8⁺ T cell infiltration between the CR/PR group and SD/PD group. Mann–Whitney U test. CR complete response, PR partial response, SD stable disease, PD progressive disease
