When only cases of CH with HCV-related hepatitis were considered, according to the genotype involved, patients with HCV-genotype-1 infection showed a statistically higher Bax mRNA expression than in patients with HCV-genotype-3 infection (7.620 ± 3.0 vs 4.605 ± 1.70, P = 0.033) (Figure 2C). This evidence concerns the gene BAX and infection.
