3. Fig 2
Surgeon-estimated overall postoperative (within 30 days) risk of developing venous thromboembolism (VTE) for a patient undergoing an esophagectomy for any diagnosis. The American College of Chest Physicians describes VTE risk categories as very low (<0.5%), low risk (∼1.5%), moderate risk (∼3%), and high risk (∼6%). These are marked by vertical lines along the bar graph.
