The hierarchical structure of each logistic regression model assumed a random intercept accounting for differences in the use of medication between countries and adjustment was made for age, sex, BMI, alcohol intake, education, exercise and smoking status.
For each of the aircraft noise models (LAeq,16h and Lnight), adjustment was made for exposure to road traffic noise (LAeq,24h); and for the road traffic noise models, adjustment was made for exposure to aircraft noise (LAeq,24h).
