The relationship between residuals and mean of the predicted and measured values in the cross-validation group. A solid line is mean of residuals and two dashed lines are two standard deviations of the residual values. Close and open circles indicate males and females, respectively. The residual value is the difference between predicted and measured anatomical cross-sectional area (ACSA) in the quadriceps femoris
