The ROC of CRRT initiation
As we found FST to be an independent and valuable predictor, we investigated a urine output cutoff of 2 h after FST to better direct clinical work. By drawing the receiver operating characteristic (ROC) curve, the area under curve (AUC) was 0.966 (cutoff 156 ml, sensitivity 94.85%, specificity 98.04%, The ROC of urine output after FST 2 h, serum creatinine and SOFA for CRRT initiation.
