Measure at 6 months | Categorisation of self-reported current health | N | Mean | SD | t-statistic | p-value | Relative efficiency |
---|---|---|---|---|---|---|---|
EQ-5D-3 L | Very Good or Good | 68 | 0.79 | 0.23 | 6.13 | P < 0.001 | 1.57 |
Fair, Poor or Very Poor | 87 | 0.50 | 0.34 | ||||
SF-6D | Very Good or Good | 67 | 0.76 | 0.14 | 7.69 | P < 0.001 | |
Fair, Poor or Very Poor | 88 | 0.60 | 0.12 |
N is the sample size. SD denotes the standard deviation. Relative efficiency statistic is referenced at 1.0 for the EQ-5D-3 L. A relative efficiency value higher than 1.0 shows that the SF-6D is more efficient than the EQ-5D-3 L
