Potential risk factors included the total number of instances of vaginal intercourse (continuous variable), the number of new partners (0, 1, or >1), the frequency of condom use by partners (<5 percent, 5 to 49 percent, 50 to 99 percent, or 100 percent), the partner’s circumcision status (circumcised, uncircumcised, or unknown), and the partner’s number of previous partners (0, ?1, or unknown). The frequency of condom use was calculated by dividing the number of condoms used for vaginal intercourse by the number of instances of vaginal intercourse during the eight-month study period. If multiple new partners were reported during an eight-month period, the circumcision status and previous number of partners were summarized ( Table 1 ). The percentage of days that lacked diary entries was calculated to assess potential confounding created by missing data. The effect of the frequency of condom use was evaluated by multivariate analysis with the inclusion of other variables that were found to be significant (P<0.10) in univariate analyses. Similar analyses were performed to evaluate risk factors for high-risk types of HPV (16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 67, 68, 73, and 82), 20,21 low-risk types (6, 11, 40, 42, 54, 55, 57, 61, 62, 64, 69, 70, 71, 72, 81, 83, 84, and CP6108), 20,21 and types 6, 11, 16, and 18 (which are included in quadrivalent vaccine trials 22 ). To evaluate whether the effect of condom use on the risk of HPV infection differed according to the location in the genital tract, similar analyses were performed to examine risk factors for incident cervical and vulvovaginal infections.
In subanalyses, subjects whoever couples made use of condoms 100 percent of time was split up into two categories on such basis as its answers so you can practical question “Performed their partner’s dick ever reach the hole of the vagina instead of a great condom?” In the event the victims usually responded “no” for each act away from genital gender into the 7-few days period, these were coded because the that have had “no genital get in touch with as opposed to an effective condom.” Analyses was basically performed since described significantly more than, which have four types of the fresh volume away from condom play with (100 percent without any genital get Sober dating sites in touch with instead of a condom, 100 % with many or an unidentified frequency of genital contact in the place of an effective condom, and you may about three organizations less than completely, since revealed significantly more than).
