  1. Values represent n (%) for each group. DVT = deep vein thrombosis, PE = pulmonary embolism, VTE = venous thromboembolism. Bold lettering indicates the type of embolism, and the list below indicates the specific locations for each type of embolism.
  2. a = Number and percentage of patients with DVT.
  3. b = Number and percentage of patients with PE.
  4. c = Number and percentage of patients with VTE in another location.
