From: Effect of short schemes on body composition measurements using Air-Displacement Plethysmography
Panel A is the regression of body density (g/cm3) by the criterion against body density by spandex bicycle shorts for the group. Panel B is the residual plot for the group where the middle dashed line represents the mean difference between body density by the criterion - body density by spandex bicycle shorts. The upper and lower dashed lines represents ±2 SD from the mean. No bias between the techniques was observed as indicated by a non-significant P value.
