IL6 and cervical squamous intraepithelial neoplasia: The HC (median, 0.029; range, 0.002 -- 0.139) had lower IL-6 mRNA expression in PBMCs than the CC patients (median, 0.101; range, 0.006 – 0.763, p = 0.001) and CIN patients (median, 0.085; range, 0.003 – 1.74, p = 0.019) but CIN patients and CC patients had no significant difference in between (p > 0.05) (Fig. 4).
