  1. Abbreviations: NT-proBNP N-terminal pro-B-type natriuretic peptide, AKI acute kidney injury. aNon-adjusted model adjusted for none. bModel 2 adjusted for age, sex and BMI. cModel 3 adjusted for hemoglobin, creatinine, serum albumin, and covariates included in model 2. dModel 4 adjusted for and estimated blood loss, duration of surgery, urine output, intraoperative diuretics, intraoperative NSAIDs, intraoperative antibiotics, postoperative infections, and covariates included in model 3. eFully adjusted model adjusted for all covariates. Stage 1 means patients who were diagnosed as stage 1 AKI according to KDIGO 2021 guideline. Stage 2 means patients who were diagnosed as stage 2 AKI according to KDIGO 2021 guideline. Stage 3 means patients who were diagnosed as stage 3 AKI according to KDIGO 2021 guideline. KDIGO, Kidney Disease: Improving Global Outcomes
