Diagnostic Value of Systemic Inflammatory Response Index for Catheter-Related Bloodstream Infection in Patients Undergoing Haemodialysis

Figure 3

ROC curve of the inflammatory composite index for diagnosing CRBSI and identifying different bacterial types: (a) ROC curves for NLR, PLR, CAR, and SIRI to diagnose CRBSI; (b) ROC curves for CAR and SIRI to distinguish gram-negative and gram-positive bacterial infections. ROC: receiver operator characteristic; NLR: neutrophil-to-lymphocyte ratio; PLR: platelet-to-lymphocyte ratio; CAR: C-reactive protein-to-albumin ratio; SIRI: systemic inflammatory response index; CRBSI: catheter-related bloodstream infection.
