Fig 4. Receiver operating characteristics analysis for lactate, pH, CO2, ScvO2 and the development of intestinal ischemia.
Panel A lactate: Area under the ROC curve: 0.5324; sensitivity 86.44% and specificity 16.2% for a cut-off value of lactate ≥ 2mmol/l; Panel B pH: Area under the ROC curve: 0.52; sensitivity 90% and specificity 21%; Panel C CO2: Area under the ROC curve: 0.6017; sensitivity 83% and specificity 38%; Panel D ScvO2: Area under the ROC curve: 06786.; sensitivity 77% and specificity 52%; ROC = Receiver operating characteristic.
