Inter- and intradevice variation exists between DXA instruments, affecting data analysis in clinical trials.
Practitioners should be aware of potential measurement variability when using DXA in clinical trials.
StrongSupportsmedium confidence
Studies demonstrate that variation in body composition measurements exist not only between DXA instruments using fan-beam and pencil-beam technologies but also between DXA instruments produced by different manufacturers.
