Note: AOR = adjusted odds ratio, CI = confidence interval,

: significant at p<.05,

: significant at p<.01.

Age, education, and HIV status were adjusted for in the regression models looking at reported HIV risks among ACASI method vs. FTF interview method.

^a significant levels were determined using t-test comparing 2 continuous variables.
