The NRI=(15.9xplasma albumin, g/dL)+41.7x(present weight/usual weight). The NRI >100 indicates the subject is not malnourished; 97.5 to 100, mildly malnourished; 83.5 to <97.5, moderately malnourished; <83.5, severely malnourished. {blacksquare}=functionally dependent, {square}=nonfunctionally dependent.
