A: The receiver operating characteristic curves (ROC) and the areas under ROC curves for sepsis screening tools in predicting infectious causes of nosocomial fever of unknown origin; B: The ROC curve and the areas under ROC curve for procalcitonin in predicting infectious causes of nosocomial fever of unknown origin. AUC: Area under the receiver operating characteristic curve; MEWS: Modified Early Warning Score; NEWS: National Early Warning Score; qNEWS: Quick National Early Warning Score; qSOFA: Quick Sequential Organ Failure Assessment; SIRS: Systemic inflammatory response syndrome; SOFA: Sequential Organ Failure Assessment; PCT: Procalcitonin.
