As demonstrated by the nomogram, an increase in the total score was observed in patients with concomitant pneumonia, heart failure (HF), or coronary atherosclerotic heart disease (CHD), in cases where mechanical ventilation (MV) was utilised, and in instances of elevated alanine aminotransferase (ALT) and C-reactive protein-lymphocyte ratio (CLR) values, and reduced albumin levels. The gene discussed is ALB; the disease is susceptibility to pneumonia measurement.
