Different lead-time time trade-off variants should be carefully studied in order to achieve the best measurement of health-state values using this new method. </AbstractSection> Copyright The Author(s) 2013

This article examines the effect that different specifications of the time trade-off (TTO) valuation task may have on values for EQ-5D-5L health states. The new variants of the TTO, namely lead-time TTO and lag-time TTO, along with the classic approach to TTO were compared using two durations...

This paper examines the effect different specifications of the Time Tradeoff (TTO) task have on health state values. The new lead time TTO is compared to a method called lag time TTO, both in two time frames. We test whether the two methods yield comparable health state values and whether the...
