Table 6.
Relative efficiency of the ATRS across all time points
| Time Point | ATRS: Z statistic derived from Wilcoxon sign rank test | EQ-5D: Z statistic derived from Wilcoxon sign rank test | DRI: Z statistic derived from Wilcoxon sign rank test | Relative Efficiency ATRS versus EQ-5D | Relative Efficiency ATRS versus DRI |
|---|---|---|---|---|---|
| Pre-Injury/6 Week | -6.8 | -6.5 | -6.7 | (-6.8/-6.5)2 = 1.1 | (-6.8/-6.7)2 = 1.0 |
| Pre Injury/3 Month | -6.7 | -6.3 | -6.2 | (-6.7/-6.3)2 = 1.1 | (-6.7/-6.2)2 = 1.2 |
| Pre Injury/6 Month | -5.5 | -4.3 | -4.8 | (-5.5/-4.3)2 = 2.1 | (-5.5/-4.8)2 = 1.3 |
| Pre Injury/9 Month | -4.6 | -2.3 | -2.8 | (-4.6/-2.3)2 = 4 | (-4.6/-2.8)2 = 2.7 |
