Note: OR: Odds ratio, 95% CI: 95% confidence interval

Model 1 was adjusted for the level of outcome at baseline, gender, age, level of education

Model 2 was adjusted for the level of outcome at baseline, gender, age, level of education, and psychosocial work factors (quantitative job demands and control over decisions)
