Multivariate models were used to estimate the adjusted OR for the lack of proficiency in urinary incontinence and prolapse knowledge using a combination of forward and backward stepwise regression locking in age, race, income, and education. As age as a continuous variable did not have a linear relationship with the log odds of our outcomes, it was categorized it into decades of age
The urinary incontinence knowledge multivariate analysis included 209 subjects (74% of data) and the prolapse knowledge analysis included 215 subjects (75% of data) who had values for all the covariates

“—” Variables that did not achieve significance on bivariate analysis and so were not included for consideration in the multivariate model
*Being unaware of POP and no prior diagnosis of POP and FI were excluded from the final model due to collinearity (VIF ≥ 5)
**Being unaware of FI and no prior diagnosis of UI, POP, FI were excluded from the final model due to collinearity (VIF ≥ 5)
Bolded p-values are significant
