1. By occupational group. Odds ratios (OR) with 95% confidence intervals (CI) of medium versus short, long versus short and long versus medium spells, adjusted for other significant covariates in multiple logistic regression analysis (see text).
2. 1) Short = only short spells. Medium = any medium but no long spells. Long = any long spells. See figure 1.
3. 2) Adjusted for age, gender, work-place unit, follow-up time, overall demands, control, job strain and general health. Persons with long spells (n = 209) were excluded from the analyses.
4. 3) Adjusted for age, gender, work-place unit, follow-up time,violence and general health. Persons with medium spells (n = 893) were excluded from the analyses
5. 4) Adjusted for age, gender, work-place unit, follow-up time, violence, insecurity at work, duties and general health. Persons with short spells (n = 787) were excluded from the analyses.
6. 5) See table 1.
7. 6) Probability of no difference between occupational groups, χ2-test.
