  1. Coefficients are showing as incremental change in the level of severity on a pits scale where value (55555) = 0 and value (11111) = 1; Detailed results are in Appendix 1
  2. **The probability of choosing the best over the worst EQ-5D-5L profile is less than 56% in taste class 2 (calculating probability from the difference between v (11111) and v (55555) on a log-odds scale which is the pits value .2161; log (p/((1-p)) = 0.2161). In this study, taste class 2 is called the garbage class because the responses were unrelated to the ordinal attributes
