Role of international normalized ratio in nonpulmonary sepsis screening: An observational study

Figure 2 Receiver operating characteristic curve of white blood cell, neutrophil-lymphocyte count ratio, platelet, prothrombin time, international normalized ratio and quick Sequential “Sepsis-related” Organ Failure Assessment score within 24 h after admission between sepsis and nonsepsis. The results showed that the area under the curve of international normalized ratio (INR), prothrombin time (PT), neutrophil-lymphocyte count ratio (NLCR), platelet (PLT), quick Sequential “Sepsis-related” Organ Failure Assessment (qSOFA), and white blood cell count (WBC) in the diagnosis of sepsis were 0.918, 0.868, 0.83, 0.841, 0.638 and 0.599, respectively, and they were statistically significant (P < 0.05). The study indicates that the INR could be a helpful diagnostic biomarker in sepsis.
