Decision Models -- Prof. If, Discount, Min, Max, etc. Information required to parameterise the model included transition probabilities, resource use and costs and utilities. Compare EVs for all strategies and choose optimal path Simple calculation method: Clarity — Isolate your parameters and formulas Consistency — define once, use many times Efficiency — changing a single variable can affect multiple numeric expressions in the model Transparency — easier to understand the meaning of each value Sensitivity analysis — covered later Clones — covered later Always use variables!

Table 82 shows the estimates used to derive transition probabilities for conversion to RRMS in the model. Deterministic sensitivity analyses were undertaken for the base-case results for the cost per QALY outcome measures:.

However, our analysis was limited in several important ways. If you are running TreeAge Pro or earlier, please go to www.
Finally, our findings from the clinical effectiveness review relied on a population diagnosed with CIS before the revised McDonald criteria 54 reclassified many who would have previously been classified as having CIS as in fact having RRMS.
People who are alive can remain in this health state or progress to RRMS.
Positive tests, cases avoided, cases identified, etc. Enter settings as seen below. Sensitivity analysis on effectiveness only Threshold at treege value 0. The model represents, as far as possible, the clinical pathways that people would take while receiving treatment for CIS.

Mimics sampling that will be performed during PSA Generates a histogram of samples Samples centered around mean 0. Open Example 2 tree. Variables, distributions, tables, trackers Built-in functions: Overview of strategies An overview of how these strategies relate to the decision-analytic model is provided in Figure That way we can find which alternative appears to work.

SA1 — changing the time horizon to 20 years and 30 years. Numeric values for sampling sort of like a range Warning: Changing the time horizon to 30 years SA1: Adjust width of node as desired for text formatting.
Both strategies are chance nodes with branches for tumor tgeeage or tumor not eradicated Different probabilities for each set of branches TreeAge Pro Healthcare Training — Module 1 — Build Cost-Effectiveness Model. Set transition reward for Die node to 1 for payoff set 3.

Health economics methods Results of the cost-effectiveness analysis Discussion of the economic assessment of disease-modifying therapies for clinically isolated syndrome. Proportion treeaeg people discontinuing disease-modifying therapy We included the annual proportion of people who discontinued DMTs as a result of AEs in the model.
Clear Turn Off Turn On. Build Cost-Effectiveness Model Goals: Check the box Define numerically at root.
Shape of distribution Required parameters are specific to each distribution type Example: Editing distributions in Excel worksheet.
Use the Function Helper to see microhelp for built-in functions and as a guide for function argument entries. Data required for the model The model was populated with information identified from the clinical 0213 and cost-effectiveness review and supplemented with information from treeagge sources.
Until more reliable information on utility values becomes available, these results should be interpreted with caution. Applications for commercial reproduction should be addressed to:
