The Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study was conducted in Finland as a joint project between the National Public Health Institute of Finland and the NCI. The overall design, rationale, objectives, and initial results of this intervention study have been published (Ann Epidemiol 1994 Jan;4(1):1-10).
