UGT1A7 and Cirrhosis: We first verified that there was no association between the two factors (presence of a viral marker and UGT1A7 polymorphism — either genotypic or phenotypic) among cirrhosis patients: the association for the genotypic form of the UGT1A7 polymorphism had a X2 = 4.7, p = 0.45 and the phenotypic form, X2 = 0.38, p = 0.82.
