Bioelectrical impedance vector analysis evaluates cellularity and hydration in cirrhotic patients. [PDF]

World J Hepatol, 2020
Malnutrition in cirrhotic patients is correlated with mortality and a better response to liver transplantation. However, recovery of the nutritional status in these patients is a challenge due to the difficulty in establishing a reliable nutritional diagnosis.

Bioimpedance patterns and bioelectrical impedance vector analysis (BIVA) of road cyclists [PDF]

Journal of Sports Sciences, 2018
Bioelectrical impedance vector-analysis (BIVA) describes cell-mass, cell function and hydration status of an individual or a group. The goal of the present investigation was to provide bioelectrical impedance data for 525 male road cyclists (155 professionals, 79 elite, 59 elite-youth, and 232 amateurs) at the time of their optimal performance level ...
