The median MSS progression was +1.08 units\/year. There was strong correlation between MSS and clinical joint scores at baseline and followup (r = 0.72 and r = 0.81, respectively). There was weak correlation between MSS and HAQ at baseline (r = 0.29), but stronger correlation at followup (r = 0.48). There was a strong association between MSS and other characteristic radiologic features of PsA (bony proliferation, periostitis, bony ankylosis) at baseline and followup (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001).
