Fig 1 No significant differences were found in (A) disease-free survival (p = 0.280) or (B) overall survival (p = 0.564) between patients with mutated (Mt, solid line) or wild-type (Wt, dotted line) epidermal growth factor receptor (EGFR).

Fig 2 (A) The disease-free survival of pN1-N2 patients with exon deletion 19 (Ex19, dotted line) was significantly better (p = 0.001) than that of pN1-N2 patients with exon 21 L858R point mutation (Ex21, solid line). (B) The overall survival of pN1-N2 patients with Ex19 was better than that of pN1-N2 patients with Ex21, although this was not statistically significant (p = 0.123).

Fig 3 The (A) disease-free interval and (B) median survival time of pN1 patients with exon deletion 19 (Ex19, dotted line) were significantly longer compared with those of pN1 patients with exon 21 L858R point mutation (Ex21, solid line; p = 0.003 and p = 0.022, respectively).

Fig 4 (A) The disease-free interval of pN2 patients with exon 19 deletion (Ex19, dotted line) was longer than that of pN2 patients with exon 21 L858R point mutation (Ex21, solid line), although this was not statistically significant (p = 0.109). (B) No significant difference was found in median survival time between pN2 patients with Ex19 and pN2 patients with Ex21 (p = 0.856).
