Recommended protein (upper panel) and calorie (lower panel) intakes for pediatric UCD and healthy subjects. Protein (upper panel) and calorie (lower panel) intakes for pediatric UCD subjects by age group compared with closest available age groups from the recommended minimum and maximum intakes per UCD guidelines [5], RDA guidelines [11] and NHANES data (NHANES 2003–2004 for protein [9] and NHANES 2009–2010 for calories [10]). Age groups used for each data set are shown beneath the X axes. Data for the prescribed diet are mean (SE). UCD, RDA, and NHANES data for older age groups are the average of male and female data. NHANES data were not available for the youngest age group.
