  1. The table depicts the number of joints at which the indicated ultrasound lesion [that is, erosions, osteophytes, grey scale synovitis (GSS) or Power Doppler signals (PD-j)] and the respective grading (1 or 2 to 3) were exclusively identified by dorsal (Dorsal only) or palmar/plantar (Palmar/plantar only) scans. Total refers to the overall number of joints positive for the specific ultrasound abnormality (irrespective of whether it was identified by dorsal, palmar/plantar or both scans). We conducted separate analyses for small finger joints except metacarpophalangeal joints (H-PIP + H-DIP), small joints of feet (MTP or F-PIP + F-DIP) and wrists. At the knees, we compared medial plus lateral (Medial/lat.) versus suprapatellar (Suprapat.) scans. Data in parenthesis reflect the percentage of positive joints out of the total number of joints revealing the indicated ultrasound finding. F-DIP, distal interphalangeal joint of the feet; F-PIP, proximal interphalangeal joint of the feet, GSS, grey scale synovitis; H-DIP, distal interphalangeal joint of hands; H-PIP, proximal interphalangeal joint of hands; MTP, metatarsophalangeal joint; PD-j, power Doppler at joints; T, total number of patients with the specific lesion; hyphens indicate “not assessed”.
