Major features of subclinical PsA and new onset clinical PsA. The features characterising the subclinical PsA (ie, pain, joint tenderness, arthralgia and imaging determined enthesopathy) could be considered as short-term predictors of PsA development. No target joints resulted as predictors of PsA development or typical for PsA onset. ¹Peripheral arthritis was the most prevalent pattern of presentation with rates ranging from 50% to 100%. ²The mean number of swollen joints at the onset of PsA ranged from 1.5 to 3.2. ³Articular erosions detected by CR were detected between 23 and 33% of patients with newly diagnosed PsA . CR, conventional radiography; PsA, psoriatic arthritis.
