The final model obtained by stepwise regression analysis revealed that only vWF:Ag levels ≥2.35 IU/mL (RR 3.80; 95% CI 1.15–12.48, p = 0.028) and ADAMTS-13 levels ≤1.03 IU/mL (RR 2.67; 95% CI 1.12–23.82, p = 0.005) were related to DVT incidence, as shown in Table 5. This evidence concerns the gene RENBP and deep vein thrombosis.
