Cost-effectiveness plane. The cumulative present value cost (in 2015 USD; discounted at 3% annually) and the cumulative discounted DALYs averted (discounted at 3% annually) for four strategies: maintaining the status quo (PEP provision for 83% of rabid dog bite victims and 34% canine vaccination by owners; gray asterisk), expanding targets of exclusive stray canine vaccination (CV; blue squares of progressively deeper shades), expanding targets of combined stray canine vaccination and sterilization (CVS; red triangles of progressively deeper shades), and expanding targets of stray canine vaccination and female sterilization (CVFS; red circles of progressively deeper shades). Greater health benefits cannot be obtained at lower cost along the efficient frontier of strategies (black line).
