Model 1: adjusted for age (in 5-year categories); model 2: adjusted for age and smoking; model 3: adjusted for age, smoking, education, car and heating and nationality; model 4: adjusted for age, smoking, education, car and heating, nationality and employment. All models are adjusted using linear regression.
