Thrombotic complication was defined as a combination of major venous thromboembolism (VTE); any symptomatic or incidentally detected proximal deep vein thrombosis (DVT) of the lower or upper limbs, any nonfatal symptomatic or incidental pulmonary embolism (PE), and pulmonary embolism-related death) and any other deep (ie, distal, splanchnic, or cerebral) or superficial venous thrombosis.
