Meta-analyses on the effect of smoking on mortality risk.
Data have been reconstructed based on the famous Smoking and Health
Report to the Surgeon General (Bayne-Jones S et al., 1964). Data
sets can be used to evaluate the risk of smoking on overall mortality
and lung-cancer deaths, respectively. The person time is attributed
such that the rate ratios are equal to the reported mortality ratios
implicitely assuming that the data have arisen from a homogeneous age
group; more detailed information by age is not available from the
report. Note, the group of "non-smokers" actually consists of all
participants except those who are smokers of cigarettes
only. Information on real non-smokers is not available from the
published Smoking and Health Report.
