duced below in Table 4-1, suggests that both sex and age are important in serving size. Age is factored in by the model, but sex is not accounted for in the characterization of the quantity of ground-beef products consumed. The gain in precision from including sex is likely to be small compared with other elements for which data are weak or absent. The committee suggests that the final risk assessment at least note the possible role of sex for completeness and future reference.
