Values are median (IQR) or N (%).
*χ2 test was used to compare categorical variables, whereas the Mann-Whitney test was used to compare age.
†OR for preference for self-sampling compared with preference for Pap testing, derived using a multivariable logistic regression model mutually adjusted for age, highest attained education, ethnicity, marital status, smoking status and previous Pap test experience.
‡Results were considered to be significant, as the p value was <0.05, or 95% CI for OR did not include 1.00.
