^*Not enough incident samples to calculate incidence reliably

Prevalence: HIV prevalence in % of population.

Incident samples: This indicates the number of samples from HIV-infected individuals that were classified as MAA positive (excluding samples with antiretroviral drugs detected), as well as samples from HIV-infected individuals with acute or early infection.

Incidence: Annual rate in %; calculated across the whole site.

Effect: Relative risk of HIV infection (CBVCT vs. SVCT); weighted average of incidence ratios across community pairs at the site.

Site weight: % contribution of the site to the overall weighted analysis.
