Figure 4:

Varying the effectiveness of the telemedicine intervention influences the probability of cost-effectiveness at given willingness-to-pay thresholds. At a willingness-to-pay threshold of $0 (A), $20 000 (B) and $50 000 (C), the high-risk approach has a higher probability of cost-effectiveness than the population-based approach. At a willingness-to-pay threshold of $100 000 (D) and effectiveness above 15%, the population-based approach has a higher probability of cost-effectiveness than the high-risk approach.
