Note: EAC = excess attributable cases due to exposure, Obs. = total number of observed cases per age-sex group, PAR = population attributable risk.

*Cell counts of less than 5 for observed cases were suppressed to comply with confidentiality requirements.

†95% confidence intervals for the population attributable risk estimates are presented in Appendix 1, Supplementary Table 2.
