Patients with Exon 19 Deletion Were Associated with Longer Progression-Free Survival Compared to Those with L858R Mutation after First-Line EGFR-TKIs for Advanced Non-Small Cell Lung Cancer: A Meta-Analysis
Figure 5
Direct comparison of EGFR exon 19 deletions versus EGFR exon 21 L858R mutations in TKI therapy cohort in terms of HR for PFS. CI = confidence interval; EGFR = epidermal growth factor receptor; HR = Hazard ratio; PFS = progression-free survival; TKI = tyrosine kinase inhibitor.
