  • ORs and 95% CIs are derived from a repeated-measures logistic regression analysis with generalised estimating equations. Model 1 adjusted for age, sex, and occupational grade. Model 2 adjusted additionally for chronic diseases (ischaemic heart disease or stroke, asthma or bronchitis, rheumatoid arthritis or osteoarthritis, cancer, and depression) as time-dependent covariates for the year preceding the assessment of the outcome.
