Adjusted receiver operating characteristic analysis of area under the curve (AUC) for DO₂i³⁴⁰ and any stage CS-AKI for neonates in STAT categories 4 and 5, n = 463 patients. A logistic regression model after adjusting for CPB time (> 90 min, ≤ 90 min), DHCA use (yes/no), nadir NP temperature, intraoperative transfusion (yes/no), patient race (White, Black, other), ethnicity (Hispanic, non-Hispanic), and preterm gestational age (yes/no), DO₂i³⁴⁰ had the highest AUC of CS-AKI, 0.66 (95% CI = 0.60 – 0.72, sensitivity = 56.1%, specificity = 69.4%).
