Figure 7From: 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 IAP. The curve describes the association between sensitivity and specificity at different thresholds of IAP in predicting mortality. Cut-off values shown in the figure are 15.13 mmHg (true positive rate 65%, false positive rate 68.3%), 17.09 mmHg (true positive rate 76.9%, false positive rate 50%) and 18.87 mmHg (true positive rate 82.9%, false positive rate 25%). ROC curves that approach the upper leftmost corner represent highly accurate studies - in this case AUC is 0.703. Accuracy of IAP in predicting mortality is fair, and ROC curve analyses is statistically significant - p value 0.021.Back to article page
