1 Crude odds ratio (OR). 2 OR with 95 % confidence interval (CI), adjusted for year of birth and age. If expected values were less than 5, Fishers exact test was used with stratification by year of birth (2 levels) and sex. 3 Ever working in these occupations. 4 OR with 95 % confidence interval (CI) adjusted for year of birth. If expected values were less than 5, Fishers exact test was used with stratification by year of birth (2 levels). 5 Ever working in high temperatures. 6 Ever working with chemicals with hormonal effects. 7 Ever working with pesticides.
