TMB and Tumor PD-L1 Expression Identify Distinct
and Independent Populations of NSCLC
Tumor PD-L1 expression

a
Symbols (dots) in the scatterplot may represent multiple data points, especially for patients with <1% tumor PD-L1 expression. The black line shows the relationship between TMB and PD-L1
expression as described by a linear regression model;
b
Among patients in the nivolumab +ipilimumab and chemotherapy arms; TMB ≥10 mut/Mb, n = 299; TMB <10 mut/Mb, n = 380
