图1A，B示出了由先前的BIA方程式估计出的ALM之间的关联（见<br>方法部分），并通过DXA得到的ALM。行列式系数只是中度<br>（R 2 = 0.49分别为0.44和男性和女性）。图1C中，示出了d年龄之间的相关性<br>和残余通过DXA和由以前的BIA方程式估计出的ALM获得的ALM的。<br>随着年龄的增长残留显著相关，和以前BIA方程低估ALM <br>青壮年。因此，前面的公式不能用于检查与年龄相关的ALM损失。

Figure 1A,B shows the association between the ALM estimated by the previous BIA equation (see<br>methods section) and the ALM obtained by DXA. The determinant coefficients were just moderate<br>(R 2 = 0.49 and 0.44 for men and women, respectively). Figure 1C,D shows the correlation between age<br>and the residual of the ALM obtained by DXA and the ALM estimated by the previous BIA equation.<br>The residual significantly correlated with age, and the previous BIA equation underestimated ALM in<br>young adults. Thus, the previous equation cannot be used to examine age-related ALM loss.
