ALB and acute kidney injury: Multivariate logistic regression revealed that the predictors of AKI were preoperative albumin level of ≤3.9 g/dL (OR 2.59, CI 1.31–5.13; p < 0.01), aneurysmal SAH (OR 3.91, CI 2.06–7.42; p <0.01), male sex (OR 3.39, CI 1.65–6.97; p<0.01), vasopressor use (OR 0.197, CI 0.057–0.676; p<0.01), and hemoglobin level (OR 0.72, CI 0.59–0.89; p< .01) (Table 2).
