Details

GNRI consists of two parts, GNRI_1 is calculated from albumin level, and GNRI_2 is calculated from body weight. When grouping according to the cut value, first judge according to the total score of GNRI. If a subject has only one of GNRI_1 and GNRI_2, then if he has reached the highest level of grouping requirements, he will also be grouped. Otherwise, it will not be grouped.

• GNRI = (1.489 * Alb(g/L)) + (41.7 * (weight(kg)/IBW(kg)))
