Table 5.
Effect sizes between CHD severity groups
| Index score | Difference between CHD only and no CHDa | Difference between CHD + meds and CHD onlya | Difference between CHD + meds and no CHDa |
|---|---|---|---|
| Proxy CVD score | 0.51 | 0.62 | 1.13 |
| EQ-5D | 0.32 | 0.52 | 0.84 |
| QWB-SA | 0.52 | 0.36 | 0.88 |
| HUI2 | 0.31 | 0.72 | 1.03 |
| HUI3 | 0.28 | 0.81 | 1.09 |
| SF-6D | 0.36 | 0.58 | 0.94 |
| SF-36 MCS | 0.24 | 0.22 | 0.45 |
| SF-36 PCS | 0.49 | 0.97 | 1.46 |
| HALex | 0.57 | 0.93 | 1.50 |
For effect size calculation, differences in mean HRQoL scores were standardized to population standard deviation among those without CHD from Table 4. Root mean squared error for model with index score as outcome and CHD group and adjustment variables (age, sex, gender) as predictors was used for standardization
