EGFR and non-small cell lung carcinoma: The meta-analysis reveals that, for EGFR mutation-positive stage IIIA NSCLC patients, compared with NCT, NTT can significantly increase ORR (relative risk [RR]:1.70, 95% confidence interval [CI]:1.35-2.15; subgroup-RR:1.56, 95% CI 1.23-2.0) and significantly reduce grade 3/4 AEs (RR:0.5, 95% CI 0.34-0.75; subgroup-RR: 0.53, 95% CI 0.26-1.08).
