Serum galectin-3 levels at ICU admission predict subsequent acute kidney injury and ICU mortality among patients. Means are shown by the gray horizontal bars and displayed numerically above the corresponding columns. a Serum galectin-3 levels in AKI vs non-AKI groups following ICU admission (11.2 ± 1.6 ng/ml vs. 5.3 ± 0.5 ng/ml, p = 0.002). Red dots represent data from non-survivors, while black dots represent data from survivors. b Serum galectin-3 levels in survivor vs non-survivor groups following ICU admission (18.7 ± 3.6 ng/ml vs. 6.4 ± 0.6 ng/ml, p = 0.0002). c Area under the receiver operating characteristic curves for serum galectin-3 in survival (green curve) and galectin-3 in AKI (blue curve)
