Specifically, the cumulative incidence of thrombosis was 0% for the low-risk (t-PA ≤4 ng/mL), 8% (95% CI: 2.7–18%) for the intermediate (t-PA: >4 to <32 ng/mL), and 34% (95% CI: 6.9–62%) for the high-risk group (t-PA ≥32 ng/mL), with and HR of 4.7 (CI: 95%: 0.88–25.2; p = 0.057). The gene discussed is PLAT; the disease is Venous thrombosis.
