Summary of input parameters for the model: HIV RNA distribution and CD4⁺ cell count decrease by HIV RNA level.

HIV RNA level, copies/mL	Proportion of cohort^a	Monthly decrease in CD4⁺ cell count, mean cells/mm³^b
0–500	0.2573	3.025
501–3000	0.2502	3.733
3001–10,000	0.2521	4.600
10,001–30,000	0.1633	5.400
>30,000	0.0771	6.375

NOTE. The initial mean value (±SD) for CD4⁺ cell count was 744 ± 279 cells/mm³. The mean age (± SD) of the patients was 33 ± 9.78 years.

Data are from the Multicenter AIDS Cohort Study [16].
