Predictive ability of urine output one day before continuous renal replacement therapy (CRRT) discontinuation [day minus 1 (day − 1)] for discontinuation of CRRT in the diuretics group. a Receiver operating characteristic (ROC) analysis of the day − 1 urine output for prediction of successful discontinuation of CRRT. Optimal cutoff value of the day − 1 urine output in all patients was 191 mL/day. The area under the ROC curve was 0.821 (95% CI 0.797–0.845, p < 0.001), sensitivity was 81.2% (95% CI 77.6–84.5%), and specificity was 71.6% (95% CI 68.0–75.0%). b ROC analysis of the day − 1 urine output for predicting successful discontinuation of CRRT in oliguric (urine output ≤ 400 mL/day) patients in the diuretics group. Optimal cutoff value of the day − 1 urine output was 125 mL/day. The area under the ROC curve was 0.745 (95% CI 0.692–0.798, p < 0.001), sensitivity was 72.1% (95% CI 64.6–78.8%), and specificity was 68.8% (95% CI 61.3–75.7%)
