Subcutaneous enoxaparin 40 mg once daily (OD) administered for 10 +/- 4 days

A composite endpoint of: asymptomatic proximal DVT in lower extremity detected by mandatory bilateral lower extremity venous ultrasonography; symptomatic DVT in lower extremity, proximal or distal; symptomatic, non-fatal PE; and VTE-related death.

A composite endpoint of: asymptomatic proximal DVT in lower extremity detected by mandatory bilateral lower extremity venous ultrasonography; symptomatic DVT in lower extremity, proximal or distal; symptomatic, non-fatal PE; and death (VTE-related and not VTE-related).

Symptomatic VTE (non-fatal PE and DVT in lower extremity), including and excluding VTE-related death (PE and PE cannot be excluded) up to Days 10, 35, and 90

Net clinical benefit is a composite of the primary efficacy endpoint (asymptomatic proximal DVT in lower extremity detected by mandatory bilateral lower extremity venous ultrasonography; symptomatic DVT in lower extremity, proximal or distal; symptomatic, non-fatal PE; and VTE-related death) plus major and clinically relevant non-major bleeding events.

Major vascular events included cardiovascular death, acute myocardial infarction (MI), or acute ischemic stroke. Participants may have had a vascular event in more than one category.

The components of the composite endpoint include asymptomatic proximal DVT in lower extremity detected by mandatory bilateral lower extremity venous ultrasonography; symptomatic DVT in lower extremity, proximal or distal; symptomatic, non-fatal PE; and VTE-related death.

The components of the composite endpoint include asymptomatic proximal DVT in lower extremity detected by mandatory bilateral lower extremity venous ultrasonography; symptomatic DVT in lower extremity, proximal or distal; symptomatic, non-fatal PE; and VTE-related death.

All deaths, including VTE-related deaths, cardiovascular deaths, and other deaths.

Major bleeding events were defined as events leading to >=2 g/dL fall in hemoglobin; or transfusion of >= 2 units of packed RBCs (Red blood cells) or whole blood; or leading to death. Non-major bleeding events were defined as overt bleeding not meeting the criteria of major bleeding
