Only values that used the scoring patterns for children older than 3 years, adolescents, and adults were selected

^aValues for DIAAS were calculated from the ileal digestibility of amino acids

^bValues for PDCAAS were calculated from the total tract digestibility of crude protein

^cAll values for DIAAS and PDCAAS were selected in humans, if available, growing pigs, or in growing rats in that order

^dMeasured in humans

^eMeasured in pigs

^fMeasured in rats
