There was no obvious difference in patient background (Table S1); however, PFS with EGFR-TKI treatment was worse in the CIN-high group than in the CIN-low group (HR 3.274; p = 0.005; median PFS 16.7 vs. 11.0 months, respectively; Figure 1C). Here, EGFR is linked to cervical squamous intraepithelial neoplasia.
