Disease progression in chronic hepatitis C patients with normal alanine aminotransferase levels

Figure 1 Incidence of disease progression according to serum alanine aminotransferase levels. There was an increase in the incidence of disease progression along with an increase in serum alanine aminotransferase (ALT) values for males (A) and for females (B). White, gray and black bars represent patients with ALT levels < 20 IU/L, 20-29 IU/L, and 30-39 IU/L, respectively.
