  • Note: CI = confidence interval.

  • * All index admissions (n = 620 656) were included in the analysis. Covariates and 2-way interactions adjusted for are listed in Appendix 1 (available at www.cmaj.ca/lookup/suppl/doi:10.1503/160427/-/DC1).

  • Cluster bootstrapping was used to obtain 95% CIs.
