How Accurate Are Charder's Body Composition Analyzers?

Comparing BIA results for Fat-Free Mass (FFM) to DXA is the most common method for validation of device accuracy. Charder's algorithms have demonstrated a r2=0.987 level of correlation with DXA for whole-body FFM. In addition to whole-body measurements, Charder devices are also specially designed to analyze segmental measurements accurately as well, with r2=0.962 with lower limbs.
