The frequency rate of EGFR mutations was lower in patients with solid nodules than in patients with ground-glass nodules (43.60% vs. 69.23%, P< 0.001) and was higher in patients with shorter tumor long diameters than in patients with longer tumor long diameters (3.15 ± 2.23 vs. 3.84 ± 2.56, P< 0.001). Here, EGFR is linked to neoplasm.
