Bottom: Bland-Altman analysis for the group where the middle dashed line represents the mean difference between % fat by ADP – % fat by HW. The upper and lower dashed lines represents ± 2 SD from the mean. Bias between the techniques was observed as indicated by a significant P value.Back to article page
