31.7 Displaying incremental values during roll back

The calculated incremental values of competing strategies in a cost-effectiveness tree are not automatically displayed when the tree is rolled back. The easiest way to report incremental expected values is to generate the CE analysis text report as described in the previous chapter. It is possible, however, to display incremental values in the rolled-back tree.

For a visual display of incremental values in the rolled-back tree, you need to create terminal node columns that display the appropriate incremental values, and then collapse the subtrees to the right of the decision node. Terminal node columns, covered in detail in the Display terminal columns/roll back columns can be used to display incremental values to the right of visual end nodes (not just terminal nodes) during roll back.
