  • *Although 300 participants were entered into the regression model, only 199 participants were used in computing ORs for the variables above, because logistic regression models use list-wise deletions for in the regression process. Thus participants that have missing values for any of the variables above will be removed in the regression process and will not be used in computing ORs. That is, only 199 participants have non-missing values for all the variables above. AORs were adjusted for all the variables shown in the table.

  • AOR, adjusted OR; STI, sexually transmitted infection.
