Table 8 Cost-effectiveness. Estimated cost-effectiveness ratio as the fraction of active cases vary, with all parameters otherwise equal to the base case scenario. All QALYs and costs are discounted at three percent per year; costs are listed in 2004 U.S. dollars. The cost-effectiveness ratios are based on the assumption that all active cases and latently infected individuals (ATS class 2 and class 4) are eligible for treatment.
