My time on the project
The CEAC is created by running probabilistic sensitivity analyses on the model used to estimate the ICER, which generates a set of possible ICERs (depending on the random selection of a variable value from the distribution of possible values associated with uncertain variables). Hundreds of different simulations are run, and ICER corresponding to the various combinations of input parameters sampled from probability distributions are plotted on the same cost-effectiveness plane. At the same time, a chart identifying the proportion of simulations in which the intervention is cost-effective (i.e. representing the probability of cost-effectiveness) is plotted on the y-axis for all potential ICER threshold values (λs) on the x-axis of the CEAC curve chart.
