Bivariate regression analyses and Bland–Altman plot for MF-BIA at 2 MHz of ZI and 5 kHz of Xc (A) The line of best fit (B) Bland–Altman plot of the difference between ALM measured by DXA and predicted by MF-BIA from the cross-validation group; Ry-y’, mean = correlation coefficient between the bias and the mean of the reference and predicted ALM; = men and = women who are within the subjective rating for good, = men and women out of the subjective rating for good
