Precision, least significant change and validity of body composition estimates from bioelectrical impedance analysis, 3D-optical scanning, and dual X-ray absorptiometry
BIA and 3DS exhibited acceptable precision for most whole-body 2C outcomes, yet measurements were not interchangeable with DXA at the individual level. These findings caution against applying cross-device normative data or clinical cut-points and underscore the limitations of substituting BIA or 3DS for DXA in general practice.
