  1. AAPC average annual percentage change, CI confidence interval
  2. aJoinpoint results are not shown for the subgroups of deceased people younger than 30 years because fewer than five colorectal cancer deaths occurred in each 5-year age group in any year
  3. bAll the rates are presented as number of deaths per 100,000 people
  4. cStatistically significant trend
