Receiver operating characteristic (ROC) curve analysis in prediction of mortality.

<p>AUC area under curve by Hanley method to calculate standard errors, CI 95% confidential intervals, Sn/Sp sensitivity/specificity, APACHE acute physiology and chronic health evaluation, SOFA sequential organ failure assessment, SAPS II simplified acute physiology score II.</p>*<p>For the severity scores, higher values are predictors of mortality; but for the C3 levels, lower values are predictors of mortality.
