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).
The tool opens with these values already filled in. Replace them with your own.
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)

- Fingertip lesions (points)
- Telangiectasia (2)
- Abnormal nailfold capillaries (2)
- Pulmonary arterial hypertension and/or ILD (2)
- Raynaud phenomenon (3)
- SSc-related autoantibodies (3)
