From: Value of musculoskeletal ultrasound in assessment of rheumatoid hand function

  B 95% CI for B p value
Dependent variable: GAT
 (Constant) 40.29 27.19–53.39 < 0.001
 Ulnar 4 MCPJs synovitis 26.13 − 0.17 to 52.44 0.051
 Flexor tendons tenosynovitis of the ulnar 4 fingers 34.75 4.9–64.61 0.023
Dependent variable: hand grip strength
  (Constant) 200.90 187.47– 214.34 < 0.001
 Ulnar 4 MCPJs synovitis − 33.69 − 60.22 to − 7.15 0.014
 Flexor tendons tenosynovitis of the ulnar 4 fingers − 31.38 − 62.26 to − 0.5 0.037
