Figure 1. Health and Cost Outcomes of Monitoring Strategies.

Figure 1

Open symbols represent strategies that were dominated by other strategies either through strict dominance (less effective and more costly than another strategy) or extended dominance (less effective and more costly than a mix of other strategies). All CD4-based strategies were more effective and less costly than the symptom-based strategies. Starting HAART at CD4 350/μl was always more effective than starting at 200/μl, regardless of viral load monitoring. More frequent monitoring was generally more effective than less frequent, but was dominated in most cases. The squares represent the symptom-based strategies, circles represent the CD4-based strategies, and diamonds represent the CD4-viral load strategies.
