Patients who developed CIN had significantly thicker PRF (13.7 ± 4.0 mm vs. 8.9 ± 3.6 mm, p < 0.001), slightly thicker IPF (p = 0.046), and similar thicknesses of SCF (p = 0.782) and ECF (p = 0.749) compared to those who did not develop CIN. Here, KITLG is linked to cervical squamous intraepithelial neoplasia.
