  1. Esophagus, Esophagus Squamous cell carcinoma and Esophagus Adenocarcinoma among Finnish men and women aged 45–64 at beginning of each five-year follow-up period, and standardized incidence ratios (SIR) with 95% confidence intervals (CI) in 1971–95, by social class and period. Reference: economically active Finnish population.
  2. * The addition of squamous cell and adenocarcinoma cases does not sum up with "total" due to cases with other histological diagnosis.
