  1. 1 Ratio of GM TBHg in the infected (or vaccinated) group compared to the reference group. Ratio of > 1.0 suggests positive and < 1.0 suggests negative association.
  2. 2 Statistical significance tested using two-tailed t-test, alpha level of 0.05.
  3. 3 Adjusted for estimated MeHg intake, ethnicity, household income, education attainment, country of birth, alcohol intake, age, body-mass index, HBV and HCV status. HAV analysis 2001–2006 only.
  4. 4 As for (c), except HBV and HCV status, and including HIV status.
  5. 5 As for (c), except HCV status.
