Key clinical point: The addition of ultrasound-detected features, such as tenosynovitis and enthesitis, to the CASPAR (ClASsification criteria for Psoriatic Arthritis) scoring system improved its diagnostic utility.
Major finding: Specificity improved (84.0% to 91.4%) and sensitivity was similar (94.5% to 95.7%) after ultrasound features, such as tenosynovitis and enthesitis, were integrated in the original CASPAR criteria which had been based on physical examination.
Study details: Findings are from a cross-sectional study including 326 participants, of which 164 were diagnosed with PsA.
Disclosures: This study was supported by the Interdisciplinary Clinical Research Project of the Peking University First Hospital, China, and other sources. The authors declared no conflict of interests.
