Table 1.
Costs, benefits, and incremental cost-effectiveness ratios for control strategies. Costs are in 2010 USD, and both costs and life-years saved are cumulative over ten years and discounted to present-value terms with a 3% discount rate. Dominated strategies, which are italicized, are those which are more expensive and which provide less benefit than another strategy orcombination of strategies.
