Raw numbers and percentages are presented for descriptive purposes to indicate the frequencies of errors and problems across sex events among men and women with and without STD's. However, to account for nonindependence of outcomes across repeated sex events for the same persons, odds ratios comparing those with and without STD's are estimated (Est OR), 95% confidence intervals (CI) are provided, and P values are obtained via generalized estimating equations.
