¹ International Classification of Diseases (ICD) version 10.

² In the calculation of the overall SIR we included people who were >= 20 years.

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 Medium duration of employment corresponding to 6–12 years of income.

⁵ Long duration of employment corresponding to more than 12 years of income.
