Figure 2.

Utilities and costs for health states defined by CD4 counts.Note: Each expression labeled “p(t)” corresponds to a probability drawn from the effectiveness scenarios listed in Table 2. For example, element p(t) for x1 (the probability that the intervention would be associated with an increase in CD4 causing movement of patients from one group to another) would be 5% for the minimally effective scenario (first line of Table 2).
