From: Can the general public use vignettes to discriminate between Alzheimer’s disease health states?

Health state EQ-5D-5La QoL-ADb
Mean Mean

  1. CI confidence interval, QoL-AD Quality-of-life – Alzheimer’s Disease
  2. aEQ-5D-5L responses were converted into health utility scores (0 = death; 1 = perfect health); means and mean differences were rounded to two decimal places
  3. bScore range 13 to 52: lower scores indicate poorer health-related quality-of-life
  4. c p <0.0001
