TTR and infection: Among the 37 children with AB-BSI, the proportion of white blood cells (p = 0.000), the proportion of neutrophils (p = 0.042), the proportion of eosinophils (p = 0.029), the absolute neutrophil count (p = 0.000), the absolute lymphocyte (p = 0.000), the ratio of neutrophils to lymphocytes (p = 0.011), hemoglobin (p = 0.001), platelets (p = 0.000), and prealbumin (p = 0.000) LDH (p = 0.017), blood gas pH (p = 0.000), and serum potassium (p = 0.002) within 24 h of infection in the death group were significantly lower than those in the survival group.
