In HCV GT1 infection, univariate analysis showed that baseline factors, younger age, male gender, pretreatment lower HCV RNA level, RVR, absence of AF, presence of fatty liver, higher alanine aminotransferase (ALT) levels, higher hemoglobin and platelet counts, and IL-28B SNP rs8099917 TT genotype, were predictors for SVR (Table 3). Here, IFNL3 is linked to atrial fibrillation.
