aExcluding prevalent cancer cases at baseline.

bP values are derived from one way anova for continuous variables and from a chi2 test for categorical variables comparing the five meat consumption groups (vegetarian, pescetarian, 1 day/wk-, 2–5 day/wk-, and 6–7 day/wk meat consumers).

cMean ± SD, all such values.
