In patients with thrombosis, indefinite anticoagulation was more common both in SN-APS and SP-aPL groups comparing with the control group (OR 3.2, 95% CI 1.8–5.8, p < 0.001, and OR 2.2, 95% CI 1.2–4.0, p = 0.008, respectively). This evidence concerns the gene FASLG and autoimmune polyendocrinopathy.
