aIn univariate analyses, washing, wiping and insertion at follow-up visits were controlled for at study site
Multivariate analyses controlled for baseline factors and potential confounders that remained significant at P < 0.05: study group, study site, age, married, educational status, women’s behavioral risk, high risk partner, cohabitation, postive curable STI at baseline
