  • * For a specific characteristic level, the tabulated value is the ratio of the odds of being unvaccinated for the reference.

  • Reference level for the logistic regression analysis. The tabulated value for a characteristic level is the ratio of the odds of being unvaccinated for the reference level of the characteristic, compared with the odds of being unvaccinated for the characteristic level (2001 NIS).
