Figure 3. — An exon 21 L858R EGFR mutation is associated with a decreased survival rate of patients with non-small cell lung cancer. (A) PFS and (B) OS were significantly decreased in patients with an EGFR mutation. P<0.001. (C) PFS and (D) OS were significantly decreased in patients carrying the 21 L858R EGFR mutation compared with patients carrying the exon Del19 mutation. P<0.001. Symbols represent censored observations. EGFR, epidermal growth factor receptor; PFS, progression free survival; OS, overall survival.
