  • Multiple imputation was applied to impute missing vascular function and ultrasound measurements.

  • Preoperative ultrasound features were preoperative inflow artery diameter, minimum vein diameter, and brachial artery flow. Baseline demographics were age, sex, race, and dialysis status. Multiple imputation was used to impute missing vascular function and ultrasound measurements.
