Bold values illustrate the number of recent versus chronic HIV-1 infection sequences include or non-include in HIV-1 transmission clusters.
Table presents the summary statistics of the demographic, epidemiologic, clinical, and risk factors of HIV-1-infected individuals associated with inclusion in or not in clusters.
EIA, enzyme immunoassay; RITA, recent infection testing algorithm.
