^*Of the 15,641 ARIC participants considered eligible for the ARIC Cancer cohort because they consented to cancer research and were linkable to registry data, we excluded 906 participants with a prevalent cancer at baseline and 47 participants who reported a race/ethnicity other than Black or White from this table.
