HR, hazard ratio; CI, confidence interval. Note: Each row reflects separate Cox models for the given complication.

Adjusted for confounding variables: age, chronic obstructive pulmonary disease, preoperative sepsis/septic shock, cancer, preoperative acute renal failure/dialysis, preoperative ascites, estimated glomerular filtration rate, and operative procedure.

The CI for “One or More Complications” is a 95% CI. The CI for individual complications is a 99.3% CI. Note: Each row reflects separate Cox models for the given complication.
