Conclusions: Internet-based smoking cessation interventions can help large numbers of smokers quit. Large-scale international outcome studies can be successfully implemented using automated Internet sites. Interpretation of the studies’ results can be aided by extrapolating from results obtained from subsamples that are followed up by phone or similar cohort maintenance methods.
