Diagnostic power of the biomarkers and different models for ASA-AKI. a ROC curves of plasma S100A8/A9, PTX3, and CHI3L1 levels in the model construction cohort. b ROC curves depict the performance of the clinical model with the inclusion or exclusion of the Cleveland Clinic score, urinary NGAL, or plasma levels of novel biomarkers (S100A8/A9, PTX3, and CHI3L1) at 0 h postoperatively for predicting ASA-AKI. PTX3, pentraxin 3; CHI3L1, chitinase 3-like 1; ASA-AKI, acute type A aortic dissection surgery-associated acute kidney injury; ROC, receiver operating characteristic; NGAL: neutrophil gelatinase-associated lipocalin; AUC, area under the curve; CI, confidence interval
