Cost-effectiveness Markov model

Before analyzing the tree, changes can be made to certain parameter values including costs and probabilities, as may be appropriate. The default values are displayed in the table below.

Set the values to be used for each parameter when the tree is calculated. These should be your best estimates of the values in question; use of a value range for purposes of sensitivity analysis will be addressed later. Press Submit to validate the new values and update the tree. If there are problems with any values, alert messages will be displayed.

Before updating or analyzing the underlying tree, you can also see a graphic of the model, showing structure and current parameter definitions. To see the changes you make to parameter values reflected in the tree before you analyze the model, simply press Validate instead of Submit, and then click on the link above to look at the tree graphic.

Question marks (a "?") provide links to detailed information about particular model inputs.
