EGFR and AIDS dementia complex: Among EGFR‐mutated SCC (n = 78) and matching ADC (n = 78) patients, no significant difference in PFS and OS was found between the two groups (Figures 3A and 4A), although PFS and OS were slightly better in matching ADC patients than those in EGFR‐mutated SCC across subgroups such as age, gender, clinical stage, KPS, smoking history, and EGFR mutation type.
