Formula: GNRI is a composite nutrition-risk index; lower totals indicate higher risk.

GNRI has broad validation in geriatric and chronic disease cohorts as a prognostic nutrition-risk indicator.
Lower GNRI scores indicate higher nutrition-related risk and support proactive intervention.
Use for nutrition-risk stratification in older adults, especially in medically complex populations.
Cutoff performance varies by population and disease context; integrate with full clinical nutrition assessment.
