  • a Asym, aymptomatic; nonadherence, naive, failure, and interruption refer to antiretroviral therapy.

  • b As measured by the Chiron bDNA assay, with a detection limit of 50 copies/ml.

  • c Level of heterogeneity observed in HIV-1 RNA derived from 0.1 ml of plasma; low, 1 to 3 distinct bands; mod, 1 to 3 distinct bands with smears or 4 to 6 distinct bands; high, >6 bands with or without smears. Mod, moderate.

  • d Coculture day on which supernatants were collected for HIV-1 RNA isolation.

  • e Average release of p24 in supernatants of pooled wells (number of wells pooled).

  • f Coreceptor usage of isolated virus was evaluated with U87-CD4 cell lines expressing CCR5 (R5) or CXCR4 (X4). R5 in parentheses indicates minor usage of CCR5.

  • g ND, not determined.
