Rates per 100,000 workers
Crude rate: Wald 95% CI. Std. rate: age- and sex-standardized to the total study population
ᵃ For the Total column, the standardized rate is replaced by the crude rate. The population-weighted mean of size-specific standardized rates does not constitute a standard epidemiological measure; direct standardization of the entire study population to its own age–sex distribution yields the crude rate
