Abbreviations: PD ≥ 1/≥ 2 Power Doppler score ≥ 1/≥ 2 in the wrist (radio-carpal, mid-carpal and radio-ulnar joints), ECU Extensor carpi ulnaris tendon, MCP Metacarpophalangeal joint, PIP Proximal interphalangeal joint, MTP Metatarsophalangeal joint, TP Tibialis posterior tendon, n Number of patients

PD activity is based on scores ≥ 1 or ≥ 2 detected in at least one joint/tendon in the hands (wrist, MCP joints 1–5, PIP joints 2–3, ECU tendon bilaterally) versus other regions (elbow, knee, ankle, MTP joints 1–5, TP bilaterally)
