Figure 3A/B: — (A) Average daily serum creatinine values (mg/dL) are displayed from preoperative measurements through postoperative day-10, with AKI defined according to KDIGO criteria. Blue line represents average creatinine values for non-AKI patients. Red line represents AKI group with <10.4mL/kg removed using CUF (1^st Quartile,Q₁), and orange line represents AKI group with >32.6mL/kg removed using CUF (3^rd Quartile,Q₃). Higher volume removed by CUF was associated with worsening AKI. (B) Kaplan-Meier curve of 30-day survival, stratifying AKI patients that died by Youden criterion CUF volume (orange line, ≥32.9mL/kg removed, n=7; red line, <32.9ml/kg, n=15). Four patients died in the non-AKI group (blue line). Although patients with AKI had increased 30-day mortality, the relationship between mortality and CUF volume was unclear based on our results. Abbreviations:AKI=acute kidney injury; CUF=conventional ultrafiltration; KDIGO=Kidney Disease: Improving Global Outcomes.
