  1. Note: Costs are expressed in 1996 US$. "Cost-saving" indicates that the averted HIV costs exceeded the cost of the intervention. The lower and upper bound values in the multivariate sensitivity analysis represent the 5th and 95th percentiles, respectively, of the cost-effectiveness ratios generated in the Monte Carlo estimations.
