Bold signifies the 95% CI does not include 1.0.
Abbreviations: aPR, adjusted prevalence ratio; CI, confidence interval; HIV, human immunodeficiency virus; PR, prevalence ratio; Ref, reference category.
aThe PRs and 95% CIs were estimated using a log-binomial regression model.
bThe aPRs and 95% CIs were estimated using a Poisson regression with robust variance model accounting for age, race/ethnicity, cohort, and HIV risk group.
