In the high-risk group, age, BMI, lymphocyte count, albumin, prealbumin, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), lactic dehydrogenase (LDH), hydroxybutyrate dehydrogenase (HBDH), direct bilirubin, prothrombin activity (PTA), D-dimer, serum ferritin, C-reactive protein, CD3+ T cells, CD4+ T cells, CD8+ T cells, procalcitonin (PCT), pulmonary bacterial infection, and bacteremia were significantly different between the survival and mortality subgroups (Additional file 1). This evidence concerns the gene ALB and bacterial infectious disease with sepsis.
