  1. Data indicate the correlation of the inflammatory components of the bilateral and unilateral ultrasound composite scores and the 68-joint/14-entheses score with clinical measures of disease activity. CPDAI, composite psoriatic disease activity index; CRP, C-reactive protein; DAPSA, disease activity index for psoriatic arthritis; EGA, evaluator’s global assessment of disease activity; ESR, erythrocyte sedimentation rate; GS-Peri, grey scale perisynovitis; GS-Teno, grey scale tenosynovitis; GSS/GSE, grey scale synovitis/grey scale enthesitis ultrasound score; GUIS, global ultrasound inflammation subscore; PASDAS, modified psoriatic arthritis disease activity score; PD-j/e, power Doppler scores at joints/entheses; PD-Peri, power Doppler Perisynovitis; PD-Teno, power Doppler Tenosynovitis; PGA, patients’ global assessment of disease activity; Ptpain, patients’ pain assessment. ***P <0.001; **P <0.01; *P <0.05; †P <0.1; NA, no significant association found.
