Diagnostic performance of the calculated algorithm for sepsis. a) ROC curve of the algorithm for the diagnosis of sepsis. The area under the curve (AUC), the confidence intervals and the p value of significance are provided. b) Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of an algorithm value greater than 18 for the diagnosis of sepsis. c) Comparative diagnostic performance of an OB algorithm value greater than 18 and of procalcitonin (PCT) greater than 0.25‚ÄČng/ml for the diagnostic of sepsis. The p-values of the indicated comparisons are provided. CI: confidence interval
