A, comparison of the survival of patients with wild-type EGFR or any EGFR mutation in the observation arm. B, comparison of the survival of patients with wild-type EGFR or exon 19 and 21 EGFR mutations in the observation arm. C, comparison of the survival of patients with wild-type EGFR in the chemotherapy and observation arms. D, comparison of the survival of patients with exon 19 and 21 EGFR mutations in the chemotherapy and observation arms. EGFR, epidermal growth factor receptor.

3. FIGURE 2
A, comparison of the survival of patients with EGFR < high polysomy and ≥ high polysomy in the observation arm. B, comparison of the survival of patients with EGFR amplification or no amplification in the observation arm. C, comparison of the survival of patients with EGFR < high polysomy in the chemotherapy and observation arms. D, comparison of the survival of patients with EGFR high polysomy and amplification in the chemotherapy and observation arms. E, comparison of the survival of patirents with wild-type EGFR, high polysomy and amplification in the chemotherapy and observation arms. F, comparison of the survival of patients with EGFR amplification in the chemotherapy and observation arms. According to the University of Colorado Cancer Center's scoring criteria,21,22 low-EGFR gene copy number includes four categories (disomy, low trisomy, high trisomy, and low polysomy) that are less than high polysomy, whereas high EGFR gene copy includes high polysomy and amplification (≥high polysomy). EGFR, epidermal growth factor receptor.
