Meta-analysis of the association between PD-L1 expression and EGFR mutation status in non-small cell lung cancer (NSCLC) patients. (A) A forest plot of studies evaluating PD-L1 expression between EGFR wild-type and EGFR mutation patients. Pooled odds ratios of EGFR group analysis were computed using a random-effects model. (B) A forest plot of studies evaluating PD-L1 expression between EGFR Ex19del mutation and EGFR L858R mutation. Pooled odds ratios of EGFR subgroup analyses were computed using a fixed-effects model. CI, confidence interval.
