Figure 3. Inverse correlation between EGFR mutation and PD-L1 Expression (SP142).

Figure 3

Significantly fewer patients with EGFR mutation had PD-L1 TPS>50% (P=0.0003, Wilcoxon rank-sum test). (A) The height of the histogram represents the number of patients. The two panels compare EGFR WT on the left with mutant EGFR on the right. Within each panel, the first data point represents the number of patients expressing PD-L1 less than 50% and the second data point represents the number of patients expressing PD-L1 more than or at 50%. (B) EGFR versus PD-L1 expression as a continuous variable in box plot form.
