  1. MRR, mortality rate ratio; 95%CI, 95% confidence interval. All estimates are adjusted for age (5-year groups) and calendar year. Each person-interval could be in several categories at year 1. Therefore all MRRs are pairwise comparisons between the respective category in year 1 compared to electricians in year 1 (reference). The number in the reference group differed for each pairwise comparison.
