Comparison of body composition assessment by DXA and BIA according to the body mass index: A retrospective study on 3655 measures
Fig 5
Differences between fat mass and fat-free mass measurements by DXA and BIA in obese patients.
Fat mass (FM) and fat-free mass (FFM) were measured by DXA (Lunar Prodigy Advance) and BIA (BodyStat Quadscan 4000) in patients with obesity grade 1 (n = 903, upper panels), grade 2 (n = 915, middle panels) or grade 3 (n = 893, upper panels). Differences of values obtained by DXA and BIA were compared according to the BMI. The blue line represents the linear regression.
