A comparison of health utility scores calculated using United Kingdom and Canadian preference weights in persons with alzheimer’s disease and their caregivers

Table 3 Median EQ-5D-3L health utility scores

	UK-based preference weights (95 % CI)	Canadian-based preference weights (95 % CI)
Persons with AD	0.85 (0.81, 0.88)^a,b	0.84 (0.83, 0.84)^a,c
Caregivers	0.80 (0.80, 0.85) ^b,d	0.83 (0.83, 0.83) ^c,d

Note. AD Alzheimer’s disease, CI confidence interval, UK United Kingdom, Health utility scores were not calculated for three persons with AD who did not answer all of the EQ-5D-3L questions
^a p = 0.63 for median difference in persons with AD (UK versus Canadian weights)
^b p = 0.06 for median difference in persons with AD versus caregivers (UK weights)
^c p = 0.35 for median difference in persons with AD versus caregivers (Canadian weights)
^d p < 0.0001 for median difference in caregivers (UK versus Canadian weights)
