We observed a heightened prevalence of blood-thinning medication intake, including inhibitors of platelet aggregation or anticoagulants, in PD patients with the highest levels of TF (lowest tertile: 17/133 (12.8%), mid tertile: 16/139 (11.5%), highest tertile: 34/140 (24.3%), p = 0.006). The gene discussed is TF; the disease is Parkinson disease.
