a Intraplatelet serotonin levels are decreased in patients with diffuse systemic sclerosis (SSc) compared with patients with limited SSc (*p < 0.05, t test). b von Willebrand factor antigen (VWF:Ag) was evaluated in serum of patients with SSc and healthy control subjects. Higher levels are observed in patients with SSc (*p < 0.05, t test)
