Table 7 Fraction latently infected. Bivariate sensitivity analysis of base case scenario, varying the percentage of individuals in ATS classes TB3 (active cases), TB4, and TB2. The results reported are the average values for 1 000 replications, with standard errors given in parentheses. All QALYs and costs are discounted at three percent per year; costs are listed in thousands of 2004 U.S. dollars, and negative costs represent savings. All parameters are the same as in the base case scenario unless otherwise indicated; the results shown assume that treatment will be undertaken on individuals in ATS class TB2 and TB4 whenever possible.
