Survival outcomes with mefatinib were similar for patients who received mefatinib at 60 and 80 mg but were significantly different based on brain metastatic status at presentation. Kaplan–Meier curves comparing the progression-free survival (a, c) and overall survival (b, d) of patients with advanced EGFR–mutant non-small-cell lung cancer who received mefatinib as first-line therapy at a daily dose of either 60 mg or 80 mg (a, b) or based on brain metastatic status at presentation (c, d)
