Regression relationship of Work Productivity and Activity Impairment Questionnaire scores with those of the EuroQol Five-Dimensions tool and Hamburg Quality of Life Questionnaire in Multiple Sclerosis questionnaire
| Independent variable | EQ-5D | p value | HAQUAMS | p value |
|---|---|---|---|---|
| EQ-5D | −64.25 (−83.23 to −45.27) | <0.001 | – | – |
| HAQUAMS | – | – | 22.44 (18.11 to 26.77) | <0.001 |
| Age | −0.26 (−0.56 to 0.04) | 0.083 | −0.15 (−0.41 to −0.11) | 0.255 |
| Male | 3.13 (−2.55 to 8.81) | 0.278 | 4.24 (−0.78 to 9.26) | 0.097 |
| Body mass index | 0.20 (−0.55 to 0.94) | 0.601 | 0.09 (−0.59 to 0.76) | 0.800 |
| Comorbidities | 3.02 (0.15 to 5.89) | 0.040 | 0.26 (−2.34 to 2.87) | 0.843 |
Regressions use the EQ-5D and HAQUAMS measures to predict overall work impairment by the Work Productivity and Activity Impairment Questionnaire, after adjusting for age, sex, body mass index and number of comorbid conditions
