Figure 6From: Early continuous veno-venous haemofiltration in the management of severe acute pancreatitis complicated with intra-abdominal hypertension: retrospective review of 10 years' experience ROC curve. Mortality predictive values of APP. The curve describes the association between sensitivity and specificity at different thresholds of APP in predicting mortality. Cut-off values shown in the figure are 80.66 mmHg (true positive rate 57%, false positive rate 50%), 66.94 mmHg (true positive rate 85.1%, false positive rate 41.7%) and 62.26 mmHg (true positive rate 90.4%, false positive rate 33.3%). ROC curves that approach the upper leftmost corner represent highly accurate studies - in this case, the area under the curve (AUC) is 0.548. Accuracy of APP in predicting mortality has failed; also this ROC curve analysis is not significant - p value 0.583.Back to article page
