p values calculated using Mann–Whitney U test for continuous variables and Fisher's exact test or χ2 test for categorical variables. Significant values are in bold. aOne or more complication refers to the number of patients with one or more of the complications listed above. bBleeding requiring transfusion defined as intraoperative transfusion or transfusion given within the first 72 hours after surgery.
