  1. In multivariate analysis, covariates were selected by stepwise procedure (method of increasing and decreasing based on p-value threshold: both of probability to enter and probability to leave are 0.3)
  2. a hepatitis virus exposure: Seropositivity to hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb)
  3. b χ2– Test or Fisher Exact Test
  4. c Logistic regression analysis with the stepwise method: R2 = 0.0649, model p-value < 0.05, n = 240
