Furthermore, there were no significant differences in HMGA2 copy number between any of the successive CIN and cervical cancer stages (Figure 2E; CINI vs. CINII, P = 0.121; CINII vs. CINIII, P = 0.163; CINIII vs. stage I cervical cancer; P = 0.948; stage I vs. stage II cervical cancer, P = 0.288). Here, HMGA2 is linked to cervical squamous intraepithelial neoplasia.
