“…3 More recently, studies have explored the use of Discrete Choice Experiments incorporating duration (DCE TTO ) to estimate utility values anchored on the full health -dead scale. DCE TTO has been shown to produce logically consistent value sets for a range of descriptive systems in the UK, Canada and Australia, including the EQ-5D-3L, 6,7 the EQ-5D-5L [8][9][10] and the SF-6D. 11 For example, a methodological study based in the UK valued EQ-5D-5L online using DCE TTO with 1,799 members of the general population completing 15 DCE TTO choice sets s each (the PRET-AS study).…”
