Relevance of standardized phase angle and bioelectrical impedance vectors in hospitalized older patients: A cohort study

Nutrition in Clinical Practice, Volume 41, Issue 1, Page 245-254, February 2026.
Abstract Background The prognostic significance of standardized phase angle (StPhA) and bioelectrical impedance vector analysis (BIVA) remains unclear among hospitalized older individuals. Our study aimed to investigate the prognostic significance of StPhA and BIVA patterns concerning overall survival in hospitalized older patients.
