  1. CC, cervical cancer; CI, confidence interval; OR, odds ratio; STI, sexually transmitted infection.
  2. *In addition to variables in the table, odds ratios (ORs) were adjusted for age, income, education, and civil status using listwise deletion of missing observations. Model fit was good, indicated by a non-significant Hosmer-Lemeshow test (p-value = 0.15).
