  • * The model included all the variables listed in Appendix 1, Table 3. Immigration status, sex and age were forced in all models. We removed other variables that were not significant (p > 0.5), which did not affect the Bayesian Information Criterion upon inclusion and which did not modify the effect of the main exposure variable by more than 10%. Survey weights were provided by the Canadian Longitudinal Study on Aging. The full model is available in Appendix 1, Table 2.
