  1. Model 1: population density and blood lipid levels. Model 2: model 1 + sex and age. Model 3: model 2 + education. Model 4: model 3 + smoking and alcohol consumption. Model 5: model 4 + lipid modifying medication
  2. β unstandardized regression coefficient, 95%CI 95% confidence interval, population density is expressed per 1000 s of inhabitants per km2, LDL low density lipoprotein cholesterol, TC/HDL total cholesterol/high density lipoprotein cholesterol ratio, TG triglycerides
  3. aResiduals of TC/HDL and TG were not normally distributed and were therefore log transformed, this table presents log transformed data
