Follow Up
During 20 years. The date and cause of death were annually or biannually confirmed. The date of move-outs from the study area was also annually verified by the investigator in each area by reviewing population-register sheets of the cohort members. In 24 of the 45 areas, data on cancer incidence such as date of diagnosis and primary site were also collected through population-based cancer registers or by reviewing the records of local major hospitals.
