ALB and infection: Similarly, compared to patients with non-KL2/3/7/77/160 infections, a greater percentage of patients in the KL2/3/7/77/160 group underwent invasive procedures of mechanical ventilation, tracheal intubation and central venipuncture (P=0.002, P=0.001, P<0.001), and were given two or more antibiotics and carbapenem therapy prior to blood isolation (P=0.002, P=0.015), while also exhibiting lower serum albumin levels (P<0.001, P=0.002).
