Note: BP = bodily pain, LY = life years, MA = mental health — anxiety, MD = mental health — depression, PF = physical functioning, RE = role emotional, RP = role physical, SE = standard error, SF = social functioning, VT = vitality.
↵* Coefficient for the VR-12-related attribute is statistically different from the coefficient of the attribute level above, at the 5% level of significance. For the life-years attribute, the coefficient is statistically different from 0 at the 5% level of significance.
↵† Attribute levels are combined to overcome the directional inconsistencies observed in model 1. For example, in model 3, SF2 and SF3 have the same disutility (−0.021).
