‚ÄÉComparison of the relative risks (95% CI) in reducers v heavy smokers from the study of the three Norwegian counties with those presented from the Copenhagen Centre for Prospective Population Studies, both sexes*

End pointCopenhagen, DenmarkThree counties, Norway
*In the Norwegian counties, the risks are based on deaths only; in Copenhagen the same applies for cardiovascular disease and smoking-related cancer. In Copehagen, ischaemic heart disease refers to fatal and non-fatal endpoints and lung cancer to incidence.
