Trial profile
Note that search terms were applied to electronic health records to identify ever-smokers, but any patients found to be never-smokers were included in the primary analysis to maintain the pragmatic approach. GP=general practitioner. *Of 32 811 patients, 30 787 were approved to be allocated a screening questionnaire by GPs. †Percentage of all approved patients randomised in the nested trial. ‡Percentage of all eligible in cluster comparison. See appendix for a more detailed trial profile.
