HIV: human immunodeficiency virus; HPV: human papillomavirus. aHR (95% CL) = adjusted hazards ratio and 95 percent confidence limits. Wei, Lin, and Weissfeld extended Cox models were adjusted for study site, risk behavior cohort, visit year at onset of HPV infection, age group, race/ethnicity, cigarette smoking, new or multiple male sex partners, consistency of condom use, coinfection with another HPV type, and its cancer risk classification. Model for HIV-infected women was also adjusted for CD4 group (<200, 200–500, and >500 cells/μL) and logarithm of viral load.
