Examined using standard laboratory procedures. Later on dichotomized to denote transmissibility that is potentially efficient a conservative measure (viral load в‰Ґ1500 copies/mL) (Quinn et al., 2000).
Condomless genital (CVI) or anal (CAI) sex with feminine partners.Participants had been expected whether or not they involved in CVI or CAI with a main feminine partner and, if so, what that partnerвЂ™s HIV status had been (negative/positive/unknown). By cross referencing a participantвЂ™s HIV serostatus together with partnerвЂ™s observed serostatus for both CVI and CAI and summing and then dichotomizing these results, we created a dichotomous variable showing any condomless sexual activity with main feminine lovers of serodiscordant/unknown HIV status. This variable was assessed only for main female partners, in study visits 46вЂ“50 (2007вЂ“2009) only in the MACS instrument.
Possibly efficient transmission activities
We further classified condomless sex with ladies as dichotomous variables indicating possibly efficient transmission occasions if HIV good participants had viral loads в‰Ґ1500 at visits whenever condomless sex with ladies had been reported. For factors evaluated longitudinally (intimate partnership and danger), we conducted a number of general linear blended models utilizing PROC GLIMMIX in SAS 9.3 (SAS Institute, Cary, NC), using the LSMEANS declaration for team evaluations and a duplicated measures declaration with accordingly specified distributions (binary with logit link for dichotomous factors; Poisson with log website website website link for proportions) and model derived variance components. 继续阅读Condomless genital (CVI) or anal (CAI) intercourse with female partners.
