  1. Note: This specification is algebraically equivalent, but not identical, to that used by Dolan [30] in modeling time trade-off values. The slight modification from Dolan is adopted so that the modeled value for the EQ-5D state 33333 is simply equal to the sum of all of the estimated coefficients from the model, which allows for convenient rescaling (see text).
