Receiver operating characteristic curves for prognosis in CAP patients. A ROC curve was used to evaluate the predictive values for death of different biomarkers among CAP patients. B ROC curve was used to evaluate the predictive values for ICU admission of different biomarkers among CAP patients. C ROC curve was used to evaluate the predictive values for mechanical ventilation of different biomarkers among CAP patients. D ROC curve was used to evaluate the predictive values for hospital stays of different biomarkers among CAP patients
