In the final multivariable analysis, age (OR=0.924, 95%CI: 0.853–0.989, p=0.035), serum albumin (OR=0.88, 95%CI: 0.788–0.967, p=0.042), lymphocyte count (OR=0.98, 95%CI: 0.96–0.99, p=0.047), PCT (OR=1.208, 95%CI: 1.007–2.512, p=0.03), comorbidities (OR=1.947, 95%CI: 1.023–3.994, p=0.01), hypoxia (OR=2.587, 95%CI: 1.026–5.276, p=0.043), severe pneumonia (OR=2.257, 95%CI: 1.127–5.391, p=0.007) and mechanical ventilation (OR=1.998, 95%CI: 1.322–3.328, p=0.003) were all significant prognostic variables for liver injury in CAP (Table 3). Here, ALB is linked to pneumonia.
