  1. * Statistically significant. For non-stratified analyses, a p-value of 0.05 was used as the cut-off for statistical significance. Bonferroni corrections were applied for stratified analysis. For analyses by age group, a p-value of 0.01was used as the cut-off. For analyses by cause of death, a p-value for 0.015 was used
  2. ** Due to small cell counts, rates were calculated by combining annual deaths into two-year periods
