Table 3 Discriminative ability of the two EQ-5D-5L indices
From: Mapping and direct valuation: do they give equivalent EQ-5D-5L index scores?
Health indicator | Effect size (standard error) | Difference in effect size (90 % confidence interval) | |
|---|---|---|---|
Valuation-derived index score | Mapping-derived index score | ||
Oncologist-assessed performance status | 0.115 (0.012) | 0.153 (0.016) | −0.038 (−0.048 to −0.027)a |
Patient’s self-assessed performance status | 0.141 (0.010) | 0.188 (0.014) | −0.047 (−0.057 to −0.038) |
Current evidence of disease (present vs absent) | 0.122 (0.022) | 0.156 (0.029) | −0.035 (−0.053 to −0.017) |
On chemotherapy/radiotherapy (yes vs no) | 0.099 (0.022) | 0.115 (0.030) | −0.016 (−0.035 to 0.002)a |
FACT-B total score (per 20-point increment) | 0.112 (0.008) | 0.135 (0.012) | −0.023 (−0.031 to −0.015)a |
FACT-G total score (per 20-point increment) | 0.134 (0.010) | 0.165 (0.015) | −0.031 (−0.041 to −0.021)a |
EQ-VAS (per 20-point increment) | 0.100 (0.010) | 0.124 (0.014) | −0.023 (−0.032 to −0.014)a |
