Table 3. Proportion of respondents who prefer the better statement: a comparison of levels across EQ-5D-3L, EQ-5D-Y, and EQ-5D-5L.

Better statement (A)	Worse statement (B)	P (A > B)	N	P > 0.98^a
Severe problems in walking about (EQ-5D-5L Mobility, Level 4)	Confined to bed (EQ-5D-3L Mobility, Level 3)	0.96	55	0.24
A lot of pain or discomfort (EQ-5D-Y Pain/Discomfort, Level 3)	Severe pain or discomfort (EQ-5D-5L Pain/Discomfort, Level 4)	0.96	56	0.24
Very worried, sad, or unhappy (EQ-5D-Y Anxiety/Depression, Level 3)	Severely anxious or depressed (EQ-5D-5L Anxiety/Depression, Level 4)	0.90	60	0.02
Unable to walk about (EQ-5D-5L Mobility, Level 5)	Confined to bed (EQ-5D-3L Mobility, Level 3)	0.92	59	0.03
A lot of pain or discomfort (EQ-5D-Y Pain/Discomfort, Level 3)	Extreme pain or discomfort (EQ-5D-5L Pain/Discomfort, Level 5)	1.00	62	1.00

For example, 53 out of 55 respondents prefer “severe problems in walking about” over “confined to bed” (P (A > B) = 0.96)

One-sided P values for a t test on whether the proportion is >0.98. Sample size varied (55–62) due to sampling. Each respondent completed only 1 pair (no missingness)
