Relationship between TMB and PD-L1 expression and sample classifications. a Differences in TMB between PD-L1-negative, low-positive and high-positive tumours. Kruskal–Wallis test. b Proportion of samples based on PD-L1-high and TMB-high classifications in different tumour types. PD-L1-H, PD-L1 high-positive. PD-L1-LN, PD-L1 low-positive and negative. TMB-H, TMB high. TMB-ML, TMB moderate and low
