SDC1 and acute kidney injury: Multivariable logistic regression showed that both preoperative syndecan-1 concentration greater than 90 ng/mL (OR, 4.231; 95% CI, 1.249–14.33; p = 0.020) and Cleveland Clinic Foundation score (OR, 2.011; 95% CI, 1.202–3.364; p = 0.008) were independent predictors of severe AKI.
