Figure 3: Receiver-operator characteristic-curve along with 95% confidence bounds for calculating the cut-off value for sequential organ failure assessment score to predict severity. The area under the receiver-operator characteristic curve = 0.880; standard error = 0.0276; 95% confidence intervals = 0.826 to 0.922; z-statistic = 13.774; significance level P (Area = 0.5) = <0.0001. SOFA = Sequential organ failure assessment; ROC = Receiver-operator characteristic curve
