Figure 1. Survival Distribution of an Infected Cohort in Different Models.

Figure 1

Solid black line, no treatment is available. Where treatment is available, the blue line indicates that ART is available and its assumed effect is worst, the green line indicates a middle effect, and a red line indicates the effect is the best. The survival of an age and gender-matched cohort that is not infected is shown for comparison (dashed black line). The parameterisations of the ART programmes are the same as in Table 3: (A) Syndromic initiation (rule 1), monitored every 12 mo, 15% drop-out, low ANC referral, and low VCT uptake; (B) CD4 initiation (rule 7), monitored every 12 mo, 15% drop-out, low ANC referral, low VCT uptake; (C) CD4 initiation; monitored every 3 mo, no drop-out; low ANC referral, and low VCT uptake; (D) CD4 initiation, monitored every 3 mo, no drop-out, high ANC referral, and high VCT uptake.
