No significant difference of either ALT (X2 = 0.221, P = 0.638) or AST (X2 = 0.018, P = 0.895) was found between the HCV mono-infection (HIV-noninfected CHC, 44.96% for ALT and 44.18% for AST) group and the HCV/HIV coinfection (HIV-infected CHC, 41.84% for ALT and 45.92% for AST) group (Fig. 2A and B). This evidence concerns the gene GPT and infection.
