E C Keystone, M C Genovese, L Klareskog, et al. Golimumab, a human antibody to tumour necrosis factor α given by monthly subcutaneous injections, in active rheumatoid arthritis despite methotrexate therapy: the GO-FORWARD Study. Ann Rheum Dis 2009;68:789–796. Due to a programming error pertaining to CRP units used in the DAS28-CRP calculations resulted in data errors. The DAS28-CRP values were calculated with CRP in units of mg/dL instead of mg/L and therefore the DAS values in Table 1 are incorrect. Please note, the conclusions from the study remain unchanged.
The DAS values in Table 1 have been published as follows:
| Group 1 | Group 2 | Group 3 | Group 4 | Groups 3 and 4 Combined | |
|---|---|---|---|---|---|
| DAS28 using CRP | 4.860 (4.194 to 5.480) | 4.803 (4.151 to 5.558) | 5.100 (4.060 to 5.651) | 4.902 (4.320 to 5.521) | 4.931 (4.174 to 5.598) |
The correct DAS values in Table 1 should be published as follows:
| Group 1 | Group 2 | Group 3 | Group 4 | Groups 3 and 4 Combined | |
|---|---|---|---|---|---|
| DAS28 using CRP | 5.458 (4.672 to 6.093) | 5.364 (4.683 to 6.236) | 5.766 (4.628 to 6.322) | 5.393 (4.748 to 6.172) | 5.513 (4.721 to 6.271) |
