ALB and acute kidney injury: Multivariate analysis revealed that preoperative albumin level ≤3.9 g/dL was related to AKI (OR2.59, CI 1.31–5.13; p <0.01), ICU stay (OR 1.82, CI 1.47–2.25; p<0.01), and hospital stay (OR 1.87, CI 1.56–2.23; p<0.01), but not to overall mortality (HR 1.43, CI 0.91–2.25; p = 0.12).
