In a logistic regression model adjusting for covariates there were more obstructive lung functions, defined as FEV 1 % predicted below 80% and an FEV 1 /FVC ratio below 0.70, in the exposed group for men and women together, and were significant for pre-bronchodilator measurements and nearly significant (p = 0.054) for post-bronchodilator measurements compared to the control group (Table 5 ).
