Correlation between PD-L1 expression and sensitivity to EGFR-TKIs in EGFR-mutant NSCLC cells (a) Three types of EGFR-mutant NSCLC cells were treated with different concentrations of gefitinib, and the IC50 value was calculated from the dose-response survival curve determined by the CCK-8 assay. b The mRNA expression level of PD-L1 in three types of EGFR-mutant NSCLC cells was detected by qRT-PCR. ***P < 0.001
