  1. CI confidence interval, IRR incidence rate ratio
  2. aNegative binomial regressions on the incidence of diagnosed cases of melanoma by dissemination area (DA) and census year. Table presents regression results for control variables not reported in Table 1
  3. bCases of in situ melanoma are not available for Ontario in the Canadian Cancer Registry dataset in the Statistics Canada Research Data Centre so Ontario DAs are excluded from these regressions
