Table 2 Percentages of patients with PD activity at 6 and 12 months

From: Ultrasound of the hand is sufficient to detect subclinical inflammation in rheumatoid arthritis remission: a post hoc longitudinal study

  6 Months (n = 184) 12 Months (n = 152)
No joints with PD ≥ 1/≥ 2 16.5/44.0 21.4/50.9
PD ≥ 1/≥ 2 in hands as well as in other regions 40.1/18.7 37.1/14.5
PD ≥ 1/≥ 2 in hands but not in other regions 36.8/28.6 37.7/29.6
No PD ≥ 1/≥ 2 in hands but PD ≥ 1/≥ 2 in other regions 6.6/8.8 3.8/5.0
  1. 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
  2. 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)
