Note: POR = prevalence odds ratio; CI = confidence interval. All POR estimates adjusted for age, education, income, race, HIV status, gay identification, and long-term relationship status. All regression models are weighted for latent class estimation uncertainty and employ a robust standard error estimate that accounts for MSA-based sampling.
