The data presented in this table have been weighted. The denominator for the POC rapid test was n = 33,951 participants with conclusive rapid test result (it excludes rapid test discrepant result but includes participants whose IA tests were lost, rejected, or inconclusive). The denominator for IA was n = 32,716 participants with conclusive IA result (it excludes IA discrepant result but includes participants with missing or discrepant rapid test result. Participants with IA low-positive result were categorized as HIV-positive). IA: immunoassay; POC RT: Point-of-care rapid testing.
