Reference method matters: DXA system differences influence agreement with 3D optical imaging body composition estimates
Authors' conclusion
Our findings indicate that conclusions related to a clinical body composition method's accuracy depend on the specific DXA device and associated software version chosen to serve as the reference method.
Study context
- Population
- Healthy adultscompleted all four evaluations
- Participants

- Comparison
- 3D optical imaging vs three DXA systems for BF%
- Outcome
- Agreement between BF% estimates by 3DO and each DXA system
Methodological detailssame-day measurements
- Same-day measurements
Main finding
As reported in the abstract

Further findings
Method × sex and method × BMI category interactions
- Significant interactions; differences between methods not uniform across sexes or BMI categories
