ALB and acute kidney injury: Finally, in stepwise multivariable logistic regression, we found that serum albumin (OR = 0.115, 95%CI: 0.028–0.465, p = 0.002), serum sodium (OR = 1.186, 95%CI: 1.029–1.368, p = 0.019), and WBC (OR = 1.085, 95%CI: 1.004–1.172, p = 0.039) were associated with AKI occurrence.
