Association of serum gamma-glutamyl transferase with treatment outcome in chronic hepatitis B patients

Figure 4 Receiver operating characteristic curves reveal baseline gamma-glutamyl transferase levels as a predictive marker for complete response in hepatitis B e antigen-positive patients following 48 wk of nucleos(t)ide analogue treatment. Specificity and sensitivity values are plotted as a function of ALT, GGT, and HBV DNA levels. AUC is calculated with a 95%CI. ALT: Alanine aminotransferase; AUC: Area under the curve; CI: Confidence interval; GGT: Gamma-glutamyl transferase; HBV: Hepatitis B virus; ULN: Upper limit of normal.
