Values are percentages of concordant classifications across cohorts. Note the expected values for single-cell agreement, exact-quintile agreement, and adjacent-quintile agreement are 4%, 20%, and 56%, respectively. Values for women represent the NIH-AARP Diet and Health Study, Multiethnic Cohort, and Women’s Health Initiative Observational Study, whereas values for men represent the NIH-AARP Diet and Health Study and Multiethnic cohorts.
