  1. 1 International Classification of Diseases (ICD) version 10.
  2. 2 In the calculation of the overall SIR we included people who were >= 20 years.
  3. 3In the analysis of risk as a function of duration of employment we included people who were >= 30 years. Short duration of employment corresponding to less than 6 years of income was used as a reference.
  4. 4 Medium duration of employment corresponding to 6–12 years of income.
  5. 5 Long duration of employment corresponding to more than 12 years of income.
