Odds ratios of having taken sick leave for more than seven days in the past year for selected exposure variables (n=968)
| Took >7 days sick leave within past year | ||||
|---|---|---|---|---|
| Exposure variables | Odds ratio | 95% CI | Adjusted odds ratio | 95% CI |
| Adjusted odds ratios were obtained by logistic regression analysis with the covariates that were significantly related to the dependent variable. These were age, marital status, no. of years worked in factory, work section, smell chemicals, noise, poor lighting, and poor ventilation. | ||||
