*Population-based rates.
†For each category listed: the first three IRRs reflect the average change in incident rates between periods and the p values test the null hypothesis of no difference between IRRs between periods. The last IRR reflects the average annual change in incidence rates between consecutive years and the p value tests the null hypothesis of no linear trend in the incidence rate during the study period.
‡Categories with less than 5 deaths within a given time period were not reported in this table.
§P<0.05.
