Study Summary

This is a phase 4, multicenter, randomized, non-therapeutic interventional trial in subjects with psoriasis looking for the prevalence of psoriatic arthritis. Subjects will be seen and evaluated by a dermatologist at visit 1 and by a rheumatologist at visit 2. A subset of subjects will then go on to visit 3 for imaging procedures (x-ray, MRI, and ultrasound).

Primary Outcome

Percentage of participants with PsA was calculated by dividing the number of participants who were classified as positive by the rheumatologist and the total number of participants evaluated using medical history, physical examination and laboratory results as the basis for the diagnosis.
