[Mortality rates in industrial cohort studies. II. Standardized relative risk].

Presented in the paper are the features of standardized mortality rates (SMR) related to their comparability in different categories of exposure factor as well as features of standardized relative risk (SRR) of the possibility of evaluating the significance of the calculated value of relative risk and possibility of comparing SRR values in different categories of exposure factor. The method of calculating and interpreting SRR was based on the materials of the authors' own cohort study on mortality in a cohort of workers exposed to asbestos dust.
