RESULTS: High coefficients of determination (R 2) for whole-body FM (R 2= 0.94, se of estimate (SEE)= 1.2 kg), whole-body LM (R 2= 0.85, SEE= 1.4 kg), and appendicular FM (R 2= 0.82, SEE= 1.1 kg) were observed between SMF-BIA and DXA. The R 2 coefficient for appendicular LM was moderate (R 2= 0.76, SEE= 0.8 kg). Bland–Altman plots demonstrated that there was systematic (constant) bias (that is, DXA minus SMF-BIA) with overestimation of whole-body FM (bias=− 1.2 kg, 95% confidence interval (CI)=− 1.5 to− 0.1) and …
