Table 5

Full multivariate logistic regression models showing baseline determinants for excellent and poor work ability, respectively, expressed as odds ratios (OR) and their 95% confidence intervals (CI)

Determinant	Excellent work ability (n = 751)			Poor work ability (n = 857)
Determinant	Exposed cases (%)	OR	95% CI	Exposed cases (%)	OR	95% CI
The adds ratios are adjusted for all determinants in the models.
