Table 3 Electricians in year 0, who survived until year 3, their employment category the next year (year 1) and their odds of being electricians at year 2, Denmark, men

Employment status in year 1 among electricians in year 0	OR of being an electrician at year 2
	OR (95%CI)
Employed as electrician	1 (ref)
Employed not as electrician	0.02 (0.02-0.02)
Short-term sick leave	0.50 (0.45-0.54)
Long-term sick leave	0.11 (0.10-0.12)
Short-term unemployment	0.29 (0.27-0.31)
Long-term unemployment	0.26 (0.22-0.29)
Incapacity benefits	0.02 (0.01-0.02)
Comorbidity index 1-2 (medium)	0.29 (0.26-0.32)
Comorbidity index 3+ (high)	0.16 (0.11-0.23)

OR, odds 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 ORs are pairwise comparisons between the respective category compared persons employed as electricians in year 1 (reference). The number in the reference group differed for each pairwise comparison.
