Figure 2

Comparison between bioimpedance (BIA)-derived and dual X-ray absorptiometry (DXA)-assessed fat mass (in kilograms, kg). The left panel is a scatter plot of BIA-derived and DXA-assessed fat mass is shown with the best fit regression (solid red line) and 95% confidence intervals (blue dashed); Spearman ρ = 0.94 (p < 0.0001). The Bland Altman plot is shown in the right panel; average difference between BIA-derived and DXA-assessed fat mass was 2.7 ± 3.2 kg (solid red line); 95% confidence intervals are shown as blue dashed lines.
