On multivariable linear regression, Hb (β = 0.09 [SE = 0.04]), Albumin (β = 0.32 [SE = 0.09]), diastolic blood pressure (DBP) (β = 0.01[0.005), and prior history of decompensation (β = 0.98[SE = 0.39] were found to be significant factors associated with CLDQ score in patients with liver cirrhosis (Table 3). This evidence concerns the gene GSTM1 and cirrhosis of liver.
