After verification between the total cohort and the EGFR mutation testing cohort, older age was associated with an increased likelihood of having more patients with a tumor diameter >2 cm (p < 0.001), mixed GGOs with a CTR >0.5 (p < 0.001), IAC (p < 0.001), and pathologic stage IA2–IB (p < 0.001) [Table 1]. Here, EGFR is linked to neoplasm.
