In conclusion, we have derived and validated two prognostic models that were proven to be more robust than qSOFA and SOFA in predicting mortality and in ruling out the high risk of death among patients with suspected sepsis at ED admission, either undifferentiated (eqSOFA1) or definitively diagnosed with sepsis (eqSOFA2+CRP+MR-proADM). Here, CRP is linked to Sepsis.
