NOTE. Generalized estimating equations used to adjust for observations correlated within person. Odds ratios (ORs) were adjusted for hormonal contraceptive use, age, cervicitis, and cervical secretions, except sexually transmitted diseases (STDs), which were adjusted for hormonal contraceptive use and age but not for cervicitis, because ORs for these STDs may cause cervicitis. CI, confidence interval; PMNs, polymorpho-nuclear cells.
