All patients were evaluated for fulfillment of each of the 5 different criteria for PMR (Chuang et al, Bird, Jones and Hazleman, Healey, and the EULAR\/ACR criteria). At baseline, bilateral ultrasound (US) examinations of the shoulders and hips were performed. Final diagnosis was made by an experienced rheumatologist at the 12\u2010month follow\u2010up.

The EULAR\/ACR classification criteria with US showed the best discriminating capacity (AUC 0.843). Adding US to EULAR\/ACR criteria increased specificity from 74.4% to 89.7%, but decreased sensitivity from 89.5% to 78.9%. The two US items of the EULAR\/ACR criteria were significantly more frequent in patients with PMR than in controls.
