Using the Choice Sequence in Time Trade-Off as Discrete Choices: Do the Two Stories Match?

The EQ-5D-5L valuation protocol recommends combining time trade-off (TTO) and discrete choice experiments (DCEs). DCEs that include a duration attribute (DCETTO) allow modeling on the quality-adjusted life-year scale.
