HPV: Human papillomavirus; OR: odds ratio; CI: confidence interval; C. trachomatis: Chlamydia trachomatis. ^a one without information; ^b two without information; ^c Four without information. The variables “Education”, “Marital status”, “Smoking”, “Age at first intercourse”, “Number of lifetime of sexual partners” and the “Number of sexual partners in the past 3 months” were included in the multivariate model. The odds ratios have been adjusted for age as a continuous variable.
