  • MUDA was defined as a PD-score ≤1 at joints, peritendonal tissue, tendons and entheses.

  • *According to χ2 test.

  • Boolean's, Boolean's definition of remission; CPDAI-JED, joint, entheses and dactylitis domains of the Composite Psoriatic Disease Activity Index; DAPSA, Disease Activity Index for Psoriatic Arthritis; MDA, minimal disease activity; MUDA, minimal ultrasound disease activity; rem-phys, remission as judged by the treating physician.
