  1. % of previous rate = difference in incidence rate of cancer as a percentage of the rate in the previous time period [((Rate in period 2 - Rate in period 1)/Rate in period 1)*100]
  2. *Change in rate over study period = Rate in 2008–2011 - Rate in 1983–1987 time period
  3. % change over study period = Difference in incidence rate in final time period as a percentage of the rate in the first time period
  4. #p value of difference in incidence rate over study period evaluated using Poisson regression adjusted for age and sex where relevant
  5. Negative values denote a reduction in the incidence rate
