Age, systolic blood pressure (mmHg), respiratory rate (breaths/min), oxygen saturation (%), heart rate (beats/min), body temperature (°C), hemoglobin (g/L), leukocyte particle concentration (×109 cells/L), C-reactive protein(mg/L), procalcitonin (ng/mL), neutrophil–lymphocyte count ratio, lactate (mmol/L), intensive care unit, positive blood culture, and systemic inflammatory response syndrome are important biomarkers in sepsis following LASSO. Here, CRP is linked to systemic inflammatory response syndrome.
