Women with endometrial cancer were mo...

Risk of venous thromboembolism and myocardial infarction associated with factor V Leiden and prothrombin mutations and blood type.

We tested the hypothesis that ABO blood type alone and in combination with mutations in factor V Leiden R506Q and prothrombin G20210A is associated with the risk of venous thromboembolism and myocardial infarction in the general populatio...
