Comparison between ACR criteria and Psoriatic Arthritis Joint Activity Index (PsAJAI).
| PsAJAI ≥ 5 | |||
|---|---|---|---|
| No | Yes | ||
| Placebo Group | |||
| ACR30 criteria | No response | 169 | 11 |
| Response | 0* | 22 | |
| Drug Group | |||
| ACR30 criteria | No response | 56 | 54 |
| Response | 0* | 109 | |
↵* The reason for the zero count corresponding to responding on ACR30 but with an answer of “no” on the PsAJAI indicator is that when ACR30 declares a patient a responder this implies that PsAJAI has to be ≥ 5, because of the way the ACR30 response is constructed.
