  1. 1 All IRRs are adjusted for age and sex
  2. 2 p-values are given for the association with the uncategorised variables. IRRs are given for each quartile of the exposure variable
  3. 3 Housing score: a higher score denotes higher housing deprivation, i.e. poorer quality housing indicating lower socioeconomic status
  4. 4 Education: percentage of the population above 15 yrs of age having completed secondary school, i.e. a lower percentage indicating lower socioeconomic status
