1,5) For review articles, AMSTAR [23] was used to assess the quality of studies.
2,5) For intervention studies, Jadad scale [20] was used to assess the quality of studies.
3,5) For cohort, nested case-control, and case-control studies, Newcastle-Ottawa [21] was used to assess the quality of studies.
4,5) For cross-sectional studies, STROBE [22] was used to assess the quality of studies.

Notes
We would like to thank the chairs and members of the 2015 KDRIs review committee, and the 6 working subcommittees (age and physique, infants, energy & macronutrients, vitamins, minerals, and applications), for their tremendous efforts for establishing the 2015 KDRI. This project was funded by the Korean Ministry of Health and Welfare (Contract No. 2013: 12138153800; 2014: 25143119100; 2015: 25153092900).
