In addition, the influence of liver cirrhosis, BCS type, and elevated TBIL levels on patient prognosis has been confirmed.[9,14,23–27] Furthermore, Talen suggested that decreased ApoA levels may play a role in the etiology of thrombosis in patients with BCS and potentially in other patients with venous thrombosis.[28] Thus, the variables of age, sex, occupation, operation type, anticoagulant use, NEU, ALB, GLU, LDH, liver cirrhosis, BCS type, and TBIL were used to build models in the training set. This evidence concerns the gene ALB and cirrhosis of liver.
