Antiretroviral (ARV) drug use was defined as detection of at least one ARV drug. The table shows results of multivariate analysis of factors associated with ARV drug use (see Methods). Additional data for the frequency of ARV drug detection in different demographic sub-groups is shown in Supplementary Table 1. The frequency of ARV drug detection in the control and intervention arms of the study is shown in Table 3. The frequency of ARV drug detection during different 6-month intervals of the post-intervention assessment is shown in Figure 1.
Abbreviations: OR: odds ratio; CI: confidence interval; N: number of HIV-infected participants in the subgroup.
Intervention: community-based voluntary HIV counseling and testing; Control: standard voluntary HIV counseling and testing. These results refer to the first 6 months of the survey. There was no significant intervention effect after the first 6 months.
Period: <6 months: first 6 months of the post-intervention survey period; >6 months: remainder of the post-intervention survey period.
The p-values summarize the overall association of the factor with ARV drug detection.
