Figure 4From: Comparison of air displacement plethysmography to hydrostatic weighing for estimating total body density in children Top: regression of body density (g/cm3) by ADP against body density by HW for females. Bottom: Bland-Altman analysis for the group where the middle dashed line represents the mean difference between body density by ADP – body density by HW. The upper and lower dashed lines represents ± 2 SD from the mean. No bias between the techniques was observed as indicated by a nonsignificant P value.Back to article page
