Data presented as mean ± SD or n of patients (%).
aThe two groups were compared using Student’s t-test for continuous variables and χ2-test for categorical variables.
FIGO, International Federation of Gynecology and Obstetrics; T1, invasive <1/2 muscle layer; T2, invasive ≥1/2 muscle layer; T3, invasive cervical internal surface; NS, no significant between-group difference (P ≥0.05).
