Swelling and tenderness as derived from different joint counts for different scenarios of disease activity, based on DAS28 and DAS remission criteria
| Variables | DAS28: No remission DAS: No remission | DAS28: Remission DAS: Remission (Discordant remission) | DAS28: Remission DAS: No remission (Concordant remission) |
|---|---|---|---|
| Values are mean (SD). | |||
| *The residual swollen (tender) joint count involves joint captured by the comprehensive swollen (tender) joint count, but omitted by the condensed 28 joint swollen (tender) joint count. | |||
| DAS, disease activity score; DAS28, 28 joint disease activity score; SJC28, 28 joint swollen joint count; TJC28, 28 joint tender joint count; VAS, visual analogue scale. | |||
| Swollen joint count from the 44 joint count | 10.7 (7.7) | 4.1 (4.5) | 1.8 (3.0) |
| Swollen joint count from the 28 joint count | 8.0 (6.2) | 1.7 (2.3) | 1.2 (2.2) |
| Residual swollen joint count (from 16 joints)* | 2.7 (4.2) | 2.4 (3.9) | 0.6 (1.4) |
| Residual swollen joint count if SJC28 = 0 | 8.6 (10.5) | 2.6 (5.2) | 0.4 (1.1) |
| Tender joint count from the 68 joint count | 17.9 (14.8) | 8.8 (8.0) | 0.8 (1.3) |
| Tender joint count from the 28 joint count | 8.7 (7.1) | 1.9 (1.9) | 0.4 (0.7) |
| Residual tender joint count (from 40 joints) | 9.3 (9.9) | 6.9 (7.2) | 0.4 (1.1) |
| Residual swollen joint count if TJC28 = 0 | 16.3 (16.1) | 6.5 (9.7) | 0.4 (0.9) |
| Erythrocyte sedimentation rate (mm) | 30.1 (24.9) | 8.1 (8.1) | 8.6 (7.0) |
| Patient global assessment (VAS, mm) | 3.5 (2.5) | 2.5 (2.3) | 1.2 (1.6) |
| DAS28 | 4.4 (1.1) | 2.1 (0.4) | 1.7 (0.5) |
