The estimates were added for each individual and then exponentiated to obtain each risk score. Number of sex partners in the last three months was dichotomized at the median of 3 (Less than or equal to 3 versus More than 3). Age of Last Sex Partner was divided into three categories: 1) More than 5 Years Older; 2) Within Five Years of Age; 3) More than 5 Years Younger.
