Figure III.

Forest plot comparing the C-statistics for Risk Analysis Index (RAI)-only model performance versus the RAI-Procedure Complexity (RAI-PC) model for the three outcomes of interest (mortality, major complication, and prolonged length of stay [LOS]), stratified by procedure category. The RAI-PC model adjusted for procedural characteristics: procedure category (e.g., AAA repair), procedure type (endovascular versus open), outpatient versus inpatient surgery status, general anesthesia use, work relative value units, and operative time. Abbreviations: Abdominal Aortic Aneurysm (AAA); Thoracic Aortic Aneurysm (TAA); Thoracoabdominal Aortic Aneurysm (TAAA).
