Except where indicated otherwise, values are the number (%) of subjects. aDisease duration was calculated since the first non-Raynaud’s symptom of SSc; bmodified Rodnan skin thickness score; cdetermined by high-resolution computer tomography. ACA, anticentromere antibodies; ANA, antinuclear antibodies; Anti-Scl-70, anti-Scl-70 antibodies; dcSSc, diffuse cutaneous SSc; lcSSc, limited cutaneous SSc.
