Hepatitis D virus dual-infection among Chinese hepatitis B patient related to hepatitis B surface antigen, hepatitis B virus DNA and age

Figure 1 Constituent ratio of age among three infection groups’ patients and the hepatitis D virus screening positive rate of hepatitis B patients with different age. A and B: Age was compared using Kruskal-Wallis test, error bars represent 95% confidence interval. Note: The screening positive rate of hepatitis D virus in patients who were 30 years old or younger, and who were over 80 years old were 0.0%, and not shown in figure 1B. HDAg: Hepatitis D antigen; HDV: Hepatitis D virus.

Figure 2 Constituent ratio of hepatitis B surface antigen among three infection groups’ patients and the hepatitis D virus screening positive rate of hepatitis B patients with different hepatitis B surface antigen. A and B: Hepatitis B surface antigen (HBsAg) was compared using Kruskal-Wallis test, error bars represent 95% confidence interval. HBsAg: Hepatitis B surface antigen; HDAg: Hepatitis D antigen; HDV: Hepatitis D virus.

Figure 3 Constituent ratio of hepatitis B virus DNA among three infection groups’ patients and the hepatitis D virus screening positive rate of hepatitis B patients with different hepatitis B virus DNA. A and B: Hepatitis B virus DNA was compared using Kruskal-Wallis test, error bars represent 95% confidence interval. HBV: Hepatitis B virus; HDV: Hepatitis D virus.

Figure 4 Distribution of anti-hepatitis D antigen among two infection groups’ patients and hepatitis D virus RNA positive rate of patients with different anti-HDAg. A and B: Anti-hepatitis D antigen was compared using Mann-Whitney U test, error bars represent 95% confidence interval. HDAg: Hepatitis D antigen; HDV: Hepatitis D virus.
