  2. A dash (—) denotes a condition for which ORs were not calculated owing to fewer than 10 cases occurring in the given stage strata.
  3. aOdds ratio of stage among those with the condition compared with those without, adjusted for age, sex (except for breast and gynaecological cancers) and ethnicity (Māori/non-Māori). Statistically significant observations are shown in bold.
