Data are shown as median and range in parenthesis.
Ptpain, EGA and PGA were measured on a Visual Analogue Ccale (range 0–100 mm) and are expressed in millimetres.

–, not tested; CRP, C reactive protein (normal range 0–5 mg/L); EGA, evaluator's global assessment of disease activity; enthes., number of painful entheses according to Leeds, clinical MASEI or clinical MAEI+E scores; ESR, erythrocyte sedimentation rate (normal range 0–10 mm/first hour); HAQ, Health Assessment Questionnaire; dactylitis, dactylitis score; MASEI, Madrid Sonographic Enthesis Index; n, number of cases; NS, not significant; PD-dactylitis, ultrasound-defined dactylitis with PD-signals at involved joints and/or tendons; PD-j-score, power Doppler (PD)-score of joints; PD-MASEI-E, sum of entheses with PD-signals; enthesal sites were scanned according to Madrid Sonographic Enthesis Index plus lateral epicondyle; PD-perisyn, PD within peritendinous tissue; PD-teno, sum score of PD-signals related to tenosynovitis; PGA, patient's global assessment of disease activity; Ptpain, patient's pain assessment; SJ, swollen joint count; TJ, tender joint count.
