To understand the ability of the HIV-1 risk score to identify high risk couples for antiretroviral-based prevention in the setting of an implementation project, we used descriptive statistics to summarize the proportion of screened couples that had an HIV-1 risk score ≥5 and the proportion of higher-risk couples that enrolled in the Partners Demonstration Project. Analyses were done using STATA version 13.1 (StataCorp, College Station, TX).
