Summary of regression and Bland-Altman analysis before and after weight-loss compared to DXA

	Regression				Bland-Altman
	Intercept	Slope	R2	SEE	Bias	95% Limits	p Value
Before weight-loss
ADP %fat	6.6671	0.937	0.845	2.056	-4.0123	0.128 to 8.152	0.648
After weight-loss (16 months)
ADP %fat	4.9561	0.969	0.884	2.183	-3.7603	0.600 to 8.120	0.408

¹ Significantly different from 0 (p ≤ 0.05).

² Significantly different from 1 (p ≤ 0.001).

³ Bland-Altman analysis bias is the mean difference between ADP and DXA (p ≤ 0.001) with the trend between DXA and ADP not significant at any time point (i.e. no bias between techniques was observed).
