Cancer incidence by era of follow–up among 148 666 male Nordic seafarers and fishermen; 1961–2005. Statistically significant results marked in bold. [Obs=observed; SIR=standardized incidence ratio; CI=confidence interval]. Outcomes of a priori interest or with >1000 observed cases shown. When the observed number of cases is zero, the expected number is presented in parentheses.
