- GFR (D1~D3): average glomerular filtration rate from the 1st to 3rd day after surgery
- Clavien‒Dindo: Clavien‒Dindo complication grading system. Grade I complications refer to abnormalities that do not require drug treatment or surgery, microscopy or radiotherapy. Grade II complications require the use of other drug treatments other than the above treatments, such as blood transfusion and total parenteral nutrition. Grade IIIa complications do not require general anesthesia, whereas Grade IIIb complications do. Grade IV complications, such as cerebral hemorrhage, ischemic stroke and subarachnoid hemorrhage, are life-threatening and require IC/ICU management. Grade IVa complications are single-organ dysfunction, whereas grade IVb complications are multiorgan dysfunction. Grade V complications indicate the patient's death after surgery. If the patient has complications at the time of discharge, the corresponding complication level should be added with the suffix "g", indicating that follow-up is required to fully evaluate the complications
- GFR classification at M3: According to the patient's GFR and renal function at the three-month follow-up after surgery, Grade I: GFR greater than 90 ml/min/1.73 m2, normal glomerular filtration function; Grade II: GFR between 60–89 ml/min/1.73 m2, mild glomerular filtration function impairment; Grade III: GFR between 30–59 ml/min/1.73 m2, moderate glomerular filtration function impairment; Grade IV: GFR between 15–29 ml/min/1.73 m2, severe glomerular filtration function impairment; Grade V: GFR less than 15 ml/min/1.73 m2, severe glomerular filtration function impairment or end-stage renal failure
- aThe Shapiro‒Wilk test was used to check for normality, an independent sample t test was used, and the data are expressed as the means ± standard deviations
- bQualitative data were statistically described via rates or composition ratios (n, %), and categorical variables were compared via the Pearson chi-square test and Fisher’s exact test
