Observed (Obs) numbers of prostate cancer cases and standardized incidence ratios (SIRs) for men 30–49 years of age and men 50 years of age or older, respectively, in the five Nordic countries combined by occupational category. Occupational categories with 0 observed cases in the 30–49 age category or without a statistically significant SIR in either age category are excluded.
