HAQ and other self-reported health status measures in 114 patients with rheumatoid arthritis without overt arterial disease.
| Correlation with HAQ, Spearman ρ | Observed Range (Potential Range) | Women, n = 93 Median (IQR) | Men, n = 21 Median (IQR) | All, n = 114 Median (IQR) | |
|---|---|---|---|---|---|
| HAQ | — | 0 to 2.9 (0 to 3.0) | 1.13 (0.63; 1.75) | 0.75 (0.25; 1.75) | 1.13 (0.50; 1.75) |
| Damaged joint count | 0.53 | 0 to 43 (0 to 45) | 7 (2; 15) | 3 (1; 12) | 6.5 (2; 15) |
| Arthritis overall | −0.61 | 15 to 98 (0 to 100) | 75 (53; 84) | 74 (51; 89) | 74 (52; 86) |
| Health overall | −0.43 | 34 to 100 (0 to 100) | 79 (70; 86) | 80 (70; 85) | 79 (70; 86) |
| EuroQol (EQ-5D)* | −0.73 | −7 to 100 (−59 to 100) | 69 (59; 80) | 66 (52; 76) | 69 (59; 76) |
↵* EuroQol (EQ-5D) utility score has been multiplied by 100 to make it more easily comparable with the overall arthritis/health scales. A higher HAQ score and damaged joint count indicate a higher level of disability/disease severity. A higher EQ-5D overall-arthritis and overall-health score indicates better health on a scale up to 100. HAQ: Health Assessment Questionnaire; IQR: interquartile range.
