ALB and acute kidney injury: Multivariate logistic regression analysis revealed that high &Alb [odds ratio (OR) 2.495, 95% CI: 1.277–4.874, P = 0.007], male sex (OR 0.616, 95% CI: 0.389–0.976, P = 0.039), serum creatinine level (OR 1.021, 95% CI: 1.015–1.027, P < 0.001), triglyceride level (OR 0.775, 95% CI: 0.627–0.958, P = 0.019), postoperative albumin level (OR 0.911, 95% CI: 0.883–0.940, P < 0.001), hypoproteinaemia after surgery (OR 2.497, 95% CI: 1.361–4.582, P = 0.003), and triglyceride level (OR 0.775, 95% CI: 0.627–0.958, P = 0.019) were independent risk factors for the development of CI-AKI.
