Example

Skin thickening proximal to the MCP joints
No
Skin thickening of the fingers
Sclerodactyly / distal to MCP (4)
Fingertip lesions
None (0)
Telangiectasia
No
Abnormal nailfold capillaries
No
Pulmonary arterial hypertension and/or ILD
No
Raynaud phenomenon
Yes
SSc-related autoantibodies
Yes

Result: 2013 systemic sclerosis criteria score 10 — classifies as systemic sclerosis (>= 9).

What the result means

Sufficient
Skin thickening proximal to the MCPs classifies alone (9).
>= 9
Classifies as systemic sclerosis. Weighted sum of skin, fingertip lesions, telangiectasia, nailfold, PAH/ILD, Raynaud, autoantibodies. A classification, not a treatment order.

What you enter

  • Skin thickening proximal to the MCP joints (sufficient, 9)
  • Skin thickening of the fingers (points)
  • Fingertip lesions (points)
  • Telangiectasia (2)
  • Abnormal nailfold capillaries (2)
  • Pulmonary arterial hypertension and/or ILD (2)
  • Raynaud phenomenon (3)
  • SSc-related autoantibodies (3)
