Stratified analysis of specified occupational exposures with at least 50 exposed subjects among men, 176 cases and 630 referents, in the pooled material with adjustment for age and smoking
| Exposure | Duration | |||||||
|---|---|---|---|---|---|---|---|---|
| 0 years | >0, ⩽10 years | 11–20 years | ⩾20 years | |||||
| OR | 95% CI | OR | 95% CI | OR | 95% CI | OR | 95% CI | |
| The duration of exposures are divided into three categories to evaluate the dose-response relation, with those without exposure to the determinant in question as unexposed. Odds ratios (ORs) along with confidence intervals (CI) are shown. Latency requirement is 20 years. Those never exposed to the respective determinant were taken as referents. | ||||||||
