Simplistic overview of the Markov model. Represents a decision node, represents a label node, represents a chance node, represents a Markov node∗, represents a terminal node. ∗A Markov node allows events to recur over time.

3. Figure 2
Incremental cost-effectiveness ratio scatterplot of the probabilistic sensitivity analysis. The word incremental refers to the difference between two alternatives (e.g., scenario X minus the scenario IVF until the age of 41 years), Dose individualization increases live-birth rates with comparable costs relative to IVF until the age of 41. Exclusion of the expected poor responder decreases the costs marginally but also creates a loss in effectiveness compared with IVF until the age of 41 years. No treatment gives a reduction in costs and live births compared with IVF until the age of 41 years. The incremental cost-effectiveness ratios (ICER) lines of €10,000 and €20,000 represents the ratio per extra live birth compared with the tested scenarios.

4. Figure 3
Cost-effectiveness acceptability curve. The acceptability curve indicates the probability that an intervention is cost effective compared with the alternative, given the observed data, for a range of willingness-to-pay values. The cost-effectiveness acceptability curves show that if the willingness to pay is below €10,900, no treatment has the highest probability to be cost effective. If society is willing to pay more than €10,900, the scenario of dose individualization according to ovarian reserve has the highest probability to be the most cost-effective scenario.
