Table 2 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 | DAS28: Remission | DAS28: Remission |
|---|---|---|---|
| DAS: No remission | DAS: Remission | ||
| DAS: No remission | (Discordant remission) | (Concordant remission) | |
| 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) |
| DAS | 3.6 (1.1) | 2.3 (0.7) | 1.1 (0.4) |
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.
