HIV: human immunodeficiency virus.
aOR (95% CL) = adjusted odds ratio and 95 percent confidence limits.
Generalized linear mixed models with random intercept and slope based on the toeplitz matrix were adjusted for study site, risk behavior cohort, visit number, age group, race/ethnicity, cigarette smoking, illicit drug use, new or multiple male sex partners, and consistency of condom use. Model for HIV-infected women was also adjusted for CD4 group (<200, 200–500, and >500 cells/μL) and logarithm of viral load.
1Statistical interaction between trichomoniasis and vaginal Candida colonization ( ).
2No statistical interactions detected at the level.
*No odds ratios are presented for the overall HERS cohort because HIV status significantly modified the associations between trichomoniasis, vaginal Candida colonization, and HPV prevalence.
