The 12 health states defined by CD4+ counts and viral load. Also shown are the associated risks of AIDS events and quality of life (QOL) weights for each health state.

¹ Number of CD4+ cells per micro liter

² RNA copies/mL (as measured by the Roche Amplicor HIV-1 Monitor)

³ Number of events per 100 patients over a 3-month period
