... Precision and • Concern was expressed that, as presented, the DRI uncertainty values appear as "very certain" numbers, or at least surrounding that the level of confidence for all values is the same. reference values • Some suggested additional text or a specific risk characterization step to clarify the confidence in or precision of the established reference values; other options were also discussed, which included use of asterisks, a numeric grading system, or expressing values as a range.

... Failure to establish • An educated estimate from scientists was recognized as reference values: No a better alternative to not developing a reference value: decision is not an A value derived from scientific judgment offers a basis option for government managers who must act regardless of the existence of a value. • Interest was expressed in determining ways to specify relative uncertainty surrounding reference values and ways to identify controversies and concerns.

... Nutrient substances • Many expressed interest in continuing to move beyond appropriate for DRI essential nutrients; some indicated that nonessential consideration substances may require a different approach; some expressed interest in limiting DRIs to essential nutrients. Road Map for DRI Development Systematic evidence- • Such reviews were acknowledged as useful and relevant based reviews if the appropriate questions are articulated for the review.

... Guidance for Users Organizational • Some indicated the table's utility as a basic starting framework: 2×2 point to address DRI applications; some indicated that table it is overly simplistic and does not match real-world applications; some suggested it is too rigid. Distinction between • For some, the distinction is unclear; some indicated that individual and the interface between individuals and groups has been group applications missed; others suggested it is not a useful distinction if it causes a focus on applying the numbers rather than the underlying concepts.
