Comparison of body composition assessment by DXA and BIA according to the body mass index: A retrospective study on 3655 measures
Fig 2
Differences between fat mass and fat-free mass measurements by DXA and BIA in patients with low BMI.
Fat mass (FM) and fat-free mass (FFM) were measured by DXA (Lunar Prodigy Advance) and BIA (BodyStat Quadscan 4000) in patients with BMI < 16 kg.m-2 (n = 162, upper panels) and patients with BMI between 16 and 18.5 kg.m-2 (n = 217, lower panels). Differences of values obtained by DXA and BIA were compared according to the BMI. The blue line represents the linear regression.
