We considered 11 occupations and grouped them by likelihood of exposure to organic dusts, inorganic dusts and fumes.

The most common occupation was farming. Compared to people not working in any of the 11 considered occupations, those who were farmers for \u226520\u2005years were more likely to have chronic cough (OR 1.52, 95% CI 1.19\u20131.94), wheeze (OR 1.37, 95% CI 1.16\u20131.63) and dyspnoea (OR 1.83, 95% CI 1.53\u20132.20), but not lower FVC (\u03b2=0.02\u2005L, 95% CI \u22120.02\u20130.06\u2005L) or lower FEV\n                      <jats:sub>1<\/jats:sub>\n                      \/FVC (\u03b2=0.04%, 95% CI \u22120.49\u20130.58%).
