Abbreviations: F/U indicates follow-up; PE, pulmonary embolism; DVT, deep venous thrombosis; IVCT, inferior vena caval thrombosis.
Note: The denominators of the various complications only include patients who were evaluated (ie, patients lost to follow-up or dead are not included. Only a portion of the studies evaluated patients for all these events).
