Figure 1: Bland Altman analysis of the difference in body fat between individual methods and the 4-compartment model. Bias = Fat mass from 4C model - Fat mass from individual method. A. ADP vs 4C model, B . DEXA vs 4C model, C . Skinfold method vs 4C model, D. Bio-electrical Impedance vs 4C model. Solid line refers to mean bias. Dashed lines refers to mean ± 1.96 SD, open diamond - men; filled solid diamond - women.
