Figure 1

Panel A is the regression of percent fat determined by BOD POD_BH before hydrostatic weighing against percent fat determined by BOD POD_FH following hydrostatic weighing. The dotted line is the line of identity (regression slope = 1 and regression intercept = 0). The regression line significantly deviated from the line of identity. Panel B are the residuals from linear regressions of the percent fat from the BOD POD_BH on percent fat from the BOD POD_FH. The middle line represents the mean difference while the upper and lower dashed lines represent ±2 SD from the mean. No bias was observed as indicated by the non-significant P value.
