As presented in Fig. S1, Kaplan-Meier curves of progression-free survival (PFS) suggested that BMI, post-operative bladder catheterization period, human papillomavirus (HPV), pathological classification, pathological differentiation degree, adjuvant radiotherapy or chemotherapy, obstetrical history, Ki-67, estrogen receptor (ER), progesterone receptor (PR), and P53 were not significant predictors for PFS (P > 0.05 for all) in cervical cancer patients. This evidence concerns the gene MKI67 and cervical cancer.
