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.

During the subanalyses, subjects whose people used condoms 100 percent of time was indeed divided in to two categories based on the responses in order to issue “Did the lover’s knob actually ever touch the opening of snatch without a beneficial condom?” In the event the sufferers always responded “no” for each work off vaginal gender when you look at the seven-day online STD Sites dating months, these people were coded since which have had “zero genital contact without good condom.” Analyses were did while the revealed more than, which have five categories of the newest volume from condom play with (100 percent with no genital get in touch with in the place of good condom, 100 percent with some or an unidentified regularity out-of vaginal contact as opposed to good condom, and three organizations less than 100 percent, as explained above).

Likewise, Cox proportional-problems models were used to choose chance situations for the recognition from event cervical squamous intraepithelial sores in seven days in advance of a given Pap shot (on the basis of a past observation that the majority of sores exists following event illness 23 ). An excellent 51-go out lag before every go to is actually integrated as 51 months is actually new shortest observed interval between your day a woman basic had intercourse while the big date of identification away from an instance lesion in this research. Data for particularly victims were censored following the very first recognition off a case lesion.
