Bolt=studies in which contrast was used to score synovitis and tenosynovitis. Erosions were scored on a scale from 0–10 for each location; BME and synovitis were scored from 0–3 for each location. Erosions and BME were scored in 23 locations in the hand and 10 in the foot; synovitis was scored in 7 locations in the hand and 5 in the foot.
†Krabben summed the BME and the synovitis into an inflammation score.
*Is a longitudinal study with T0 as baseline, T12 after 12 weeks, T24 after 24 weeks, T52 after 52 weeks.
Dom, dominant hand; MCP, metacarpophalangeal joints; MTP, metatarsophalangeal; NP, Not provided; Wr, wrist.
