^*Red meat included all items listed, shown as listed on the FFQs. “Processed meat” included hot dogs, lunch meats, sausage, and bacon only. “Fresh” red meat included all items listed, excluding processed meats.

^†The 2003 FFQ included questions on meat preparation and therefore separated some questions from the similar 1999 survey.

^‡< 1% of participants reported consuming liver weekly in 1999; therefore, the question was omitted from the 2003 FFQ.
