Note: Study subjects were considered to be exposed if they had ever worked in an occupation with a assigned proportion of exposed workers greater than or equal to 5%. Categories derived from distribution of lifetime cumulative exposure (low exposed: bottom 30% of the cumulative exposure distribution, medium exposed: 30–60%, high exposed: 60–90%, and very high exposed: top 10%).

^a n refers to the number of INTEROCC study subjects categorized in each cumulative exposure category when using the original FINJEM.

^b n refers to the number of INTEROCC study subjects categorized in each cumulative exposure category when using the INTEROCC JEM.

^c n refers to the difference in the number of INTEROCC study subjects included in each cumulative exposure category based on the original FINJEM and INTEROCC JEM.
