a Regression between the bioelectrical impedance analysis (BIA)-measured and Dual-energy X-ray absorptiometry (DXA)-measured appendicular skeletal muscle mass (ASM) in females. Solid line, regression line. b Bland-Altman plot for difference between DXA-measured and BIA-measured ASM and the average ASM of the two methods in females. Solid line represents the mean difference (−0.49 kg); Outer dotted lines represent limits of agreement (−2.40 to 1.41 kg) (95% confidence interval). r2 = coefficient of determination; SEE = standard error of the estimate
