Figure 2.

A, Scatterplot depicting the correlation between PD-L1 tumor proportion score and PD-L1 copy number (Spearman ρ = 0.24; 95% CI, 0.10 to 0.37; P < .001). B, Scatterplot depicting PD-L1 tumor proportion score and PD-L1 to CEP9 ratio (Spearman ρ = 0.12; 95% CI, −0.025 to 0.26; P = .10). C, Violin plot depicting PD-L1 tumor proportion score in association with PD-L1 copy number status.
