Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Outcome name:The ACR score is based on the improvement with respect to the baseline assessment in painful joint (TJC) and swollen joint (SJC). A subject will have achieved an ACR20 score if they experience an improvement of 20% with respect to the baseline assessment Measure:Variation in the ACR20 score in week 24 Timepoints:Week 24 | — |
Secondary
| Measure | Time frame |
|---|---|
| Outcome name:they are defined similarly to the ACR20, but require improvements of 50% and 70%, respectively. The ACR50 and ACR70 responses in week 24 will be analyzed in the same way as the ACR20 in week 24 Measure:Variation in the ACR50 and ACR70 scores Timepoints:week 24 ; Outcome name:AGRn is the largest integer n for which a subject meets the ACR criteria that require an improvement of n%. The ordinal transformation of the ACRn will be performed in week 24 due to the known problems with occasional appendices. Measure:Changes in ACRn Timepoints:week 24 ; Outcome name:The disease activity score (DAS28) will be calculated on the basis of parameters Measure:Changes in DAS28 Timepoints:Week 24 ; Outcome name:DAS28 is a clinical index of RA activity that combines information from swollen and painful joints, the response of the acute phase and the general state of health. Measure:Variations in the EULAR Timepoints:Week 24 | — |
