The AUC/ROC analysis of MDW for infection and sepsis (0.84 and 0.86 respectively) was found to be similar to that of CRP (0.89 and 0.92 respectively) and PCT (0.83 and 0.87 respectively), suggesting comparable performance in early detection of infection and sepsis, but avoiding complexity to the laboratory work required. The gene discussed is CRP; the disease is infection.
