Flow diagram of the family cohort. * indicates probands were classified according to their index defect. In case of multiple defects, the index defect was chosen in the following order: antithrombin deficiency, protein C deficiency, protein S deficiency, FV Leiden, prothrombin 20210G>A, high factor VIII levels, and hyperhomocysteinemia.
