  1. Logistic regression was used for projecting odds ratios (OR) in univariate analysis.
  2. Variables with statistical significance were underlined when 95%CI of OR did not include 1.
  3. *Omitted due to lack of samples for analysis.
  4. HBV: hepatitis B virus; DNA: deoxyribonucleic acid; HBsAg: hepatitis B surface antigen; N: number; OR: odds ratio; CI: confidence interval; and Ref.: reference.
