Cost-effectiveness acceptability curve for the probabilistic sensitivity analysis. The curve shows the probability that the QOF was cost-effective. It was calculated as the proportion of iterations with ICERs that were less than a given cost-effectiveness threshold. The health benefit (base-case value of 3.68 per 100,000 age-adjusted mortality reduction) was randomly drawn from a normal distribution (95% confidence interval −0.80 to 8.16).
