Based on bivariate logistic regression analysis, we could not build multivariate logistic regression models due to the small number of failure of insertion for participants. Dependent variable: Failure to insert (no failure=0, failure =1).

Independent variables: age (continuous), race/ethnicity (non-Hispanic white, non- Hispanic black, Hispanic), parity (continuous), STI history (no STIs=0, one or more STIs=1).

CI= Confidence intervals

^±We excluded Asian women due to the small sample size of this group

^*Statistically significant at the p≤ .05 level.
