ALB and acute kidney injury: We primarily performed univariate logistic regression and found that GCS (OR = 0.735, p < 0.001), absolute lymphocyte count (OR = 0.520, p = 0.042), platelet (OR = 0.993, p = 0.004), hemoglobin (OR = 0.981, p = 0.012), albumin (OR = 0.926, p = 0.005), cholesterol (OR = 0.479, p < 0.001) and epidural hematoma (OR = 0.096, p = 0.023) were negatively correlated with occurrence of AKI in included TBI patients (Table 2).
