Presentation of some baseline data of randomly selected clinical trials and calculation of the average duration that each disease modifying antirheumatic drug (DMARD) was employed
| Study | Year of publication | Disease duration | No. of DMARDs | Mean years/DMARD | Radiographic score |
|---|---|---|---|---|---|
| RAPID 18 | 2008 | 6.2 | 2.3 | 2.7 | ∼38 (vdHTSS) |
| RAPID 29 | 2009 | 6.0 | 2.2 | 2.7 | ∼44 (vdHTSS) |
| OPTION11 | 2008 | 7.5 | 2.5 | 3.0 | ND |
| DANCER13 | 2006 | 10.4 | 3.4 | 3.1 | ND |
| LITHE10 | 2011 | 9.3 | 2.6 | 3.6 | ∼29 (GTSS) (≅50 vdHTSS) |
| TOWARD12 | 2008 | 9.8 | 2.6 | 3.8 | ND |
| TOTAL | 8.2 | 2.6 | 3.2 | ∼38 |
≅ rough estimation, detailed calculation difficult due to differences in scoring of individual joints and total sum.
GTSS, Genant-modified total Sharp score; ND, not done; vdHTSS, van der Heijde-modified total Sharp score.
