Bold values denote significant associations (p < 0.05).
an = 236; 3 participants had missing in variable ‘high-risk occupation (asthma)’.
bn = 236; 3 participants had missing in variable ‘high-risk occupation (COPD)’.
Regarding FEV₁ negative numbers report larger decrease. The table shows odds ratios (OR) and regression coefficients with 95% confidence intervals (95% CI).
