^*From Fisher's exact test.

^†This end point is a composite of death; deep vein thrombosis or venous thromboembolism; reintervention with the use of a percutaneous, endoscopic, or operative technique; or failure to be discharged from the hospital within 30 days after surgery. AIE, adverse intraoperative event; DVT, deep vein thrombosis; PE, pulmonary embolus.
